A demonstration of all the cool amp and effects kits from MOD Kits DIY available

No, MOD Kits are sold as "Do It Yourself (DIY)" kits. All parts are included, but the kit must be assembled and soldered using your own tools. We provide easy-to-follow instructions for all of our kits.

We have instructions for adding a DC power jack for many of our kits in their File Downloads section. Power-All offers a cable that hooks directly to the unit's battery snap and allows use with a regular 9VDC center pin negative power supply.

Bass to Tremolo Conversion Kit

This kit was designed for the guitarist who owns a silver-face Bassman and rarely uses the bass instrument channel. Turn the bass instrument channel into a foot-switchable vintage tremolo effect for the normal channel. The kit comes with parts and easy to follow instructions. You will need your own tools and solder.

6L6GC to EL34 Kit

This kit is for the guitarist who owns a vintage Fender amp that uses two 6L6GCs and wants to be able to use EL34 tubes in their place. The kit comes with electronic components, two EL34 vacuum tubes and easy to follow instructions. You will need your own tools and solder.

Tone Stack Conversion Kit

This kit is for those guitarists who want to experiment with spicing up the tone of their vintage silver-face or black-face Fender amp by modifying the tone stack components. The kits comes with parts and easy to follow instructions. You will need your own tools and solder.

Normal to Bass Conversion Kit

This kit was designed for those who play both guitar and bass. Turn the Normal Channel in your silver-face or black-face Fender amp into the Bass Instrument channel. The kit comes with parts and easy to follow instructions. You will need your own tools and solder.

Using a Gretsch 6118T in the middle position, plugged into the Trill Tremolo from modkitsDIY.com and then into AmpliTube 3.5 set to the Orange Tiny Terror's clean setting, I played a variety of settings, chords, single notes and power chords.

We recommend re-tracing each step of the assembly process using the instructions. This will allow you to insure there are no wiring errors and check the proper orientation of the transistors, diodes and polarized capacitors. The next step would be to make sure there are no unintended shorts and cold solder joints. Cold solder joints are more common when using lead-free solder as many soldering irons don't get hot enough to properly melt lead-free solder.

Not all of our Mod® Kits are still in production. You can find a list of our discontinued products on our discontinued product page.

We offer kits for builders of all skill levels. Our kits with a build difficulty of 1 should be doable, if maybe a little challenging, for a beginner. See our build difficulty guide for more information.

The label is not attached to the enclosure initially. It is up to you where you would like to put it on the pedal or if you'd like to leave it off completely.

Here is what people are saying about MOD 101 Guitar Amp Kit

"This kit was my first amp build. I had fun and learned a lot while putting it together. Now I have a great time gigging with it!" "This is a nice amp. The kit was fun to build and the instructions were great!" "I've been wanting to learn to to build my own tube amp for a long time but had no idea where to start. The MOD 101 has been my gateway to DIY amp building."

The MOD 102 is a great place to start for those interested in building their own tube amp. It is based on a classic American tube-circuit design combined with a British-style Class A output tube section. At low volume it produces a clean, chimey tone that moves into smooth overdrive at higher volumes. All parts are included along with a pre-drilled steel chassis, wire, and tubes (1 EL84 and 1 12AX7). Puts out at least 5 watts. The chassis layout is open for easy assembly using the clear, easy to follow instructions. You will need your own tools and solder.

Here is what people are saying about MOD 102 Guitar Amp Kit

"This was my first tube amp build and it was extremely easy and fun to do. I admit that I don't have enough experience with other amp kits to compare it to, but I cant imagine having a better starting point for tube amps, and the tone controls are a cool plus!" "Just the idea of this is awesome! Drive it with some P-90 dervish, dial to 10, strum chord, lean guitar against cabinet, walk across the room and have lunch while the noise self-perpetuates. Music to my ears!!!!" "Got the kit this week and finished it in about two days. Instructions and diagrams were excellent, would definitely recommend this kit for beginners. Fired up the amp for the first time and it worked perfectly. I am pretty impressed with the sound, has a nice tone and a lot more power than I would have expected."

The MOD102-F is the foreign (non-USA) version of the MOD 102 including a Hammond 369EX world power transformer instead of the 269EX. Please note: there is no power cord included with this kit (due to variations in electrical outlets around the world). You will need to find a power cord that can fit through the ¼" diameter (6.35 mm) rubber grommet hole on the rear panel. For the standard version of the MOD 102, please see K-MOD102.

Folks - just a really quick iPhone video of my Mod102+ Amp Build. REALLY happy that it worked! This was the first amp EVER that I build. Special thanks to ModKitsDIY for such an awesome project!

I just built this great sound tube drive pedal by MODKITSDIY. Its the Persuader. It took me about five hours to put it all together. This was my first attempt on making my own guitar pedal and had fun putting it all together.

Mod Reverb Tanks were carefully designed and researched to bring the warmth of a vintage sounding reverb to your amp.

What people are saying about MOD® Reverb Tanks:

"Longest decay rate of the three, very broad tone and is best suited for those who desire a long decay, ambient sounding reverb. Almost sounds like a large room. Lots of bottom end. Lots of hang time/dwell."

This is my first diy pedal that I built solo. If I can do it, you can do it.

The Aggressor is a high-gain distortion pedal kit that delivers contemporary distortion with plenty of chunk and ear-splitting pitch harmonics. The distortion effect goes from subtle break-up to over-the-top molten distortion at maximum gain.

The Aggressor features true bypass, LED indicator, and a versatile tone control with a scoop/bump switch that shifts the mid-frequency response, allowing you to craft a tone that fits your style of playing. It works well with humbuckers and single-coil pickups, so you can turn any guitar into a lethal weapon capable of inflicting serious brain damage and spontaneous combustion!

In this video, we'll demonstrate the sounds that The Aggressor from MOD® Kits DIY is capable of producing. The Aggressor is a high gain distortion pedal kit that delivers contemporary distortion with plenty of chunk and ear-splitting pitch harmonics.

The Contortionist kit is a limited edition, all analog, high octane fuzz box. It produces fuzz with layered octave overtones similar to those produced by an electronic-bow. The frequency multiplier circuitry creates harmonics that swell and recede depending on gain setting, pick attack, neck position and pickup. This is a high gain circuit that can put out up to 2 volts and will provide ample amounts of sustain.

The Contortionist II kit is an all analog, high octane fuzz box. It produces fuzz with layered octave overtones similar to those produced by an electronic-bow. The frequency multiplier circuitry creates harmonics that swell and recede depending on gain setting, pick attack, neck position and pickup. This is a high gain circuit that can put out up to 2 volts and will provide ample amounts of sustain. The Contortionist II has all the features of the original Contortionist with an added tone control for a wider range of sounds, and an LED that lights up when the unit is activated.

Tube overdrive pedal kit, limited edition. The Enticer is a limited edition tube overdrive using an RCA 12AU7. It measures 3.54" in height (to top of tube shield), enclosure is 1.35" in height, 3.70" in width and 4.70" in length.

Here is what people are saying about The Enticer:

"I spread the work on mine out over a few days and had no problems putting it together. It has an amazing tone- subtle to overdrive heaven, all in one box!" "I put this together in about 4 hours and it sounded great! It was warm and smooth, when turned up all the way it had that classic tube crunch. I am glad I got one before they were gone.." "Great sound and a cool sparkly blue finish."

The Erratic Clutch Deluxe is a unique effect pedal kit that gives you fuzzy square-wave distortion as well as a monophonic sub-octave square wave using a total of only four transistors. The two signals can be used individually or mixed together for a raw and sonically-rich synthy output. Full of character and quirk, this pedal will give you a truly original sound.

Default bias setting

 

The middle knob is the bias control. This adjusts the pulse width in the initial fuzz stage of the pedal. Set this knob to fit your pickups and playing style. The closer to the center, the longer the note will sustain; with that comes more chaotic tracking for the divider. Moving the knob clockwise or counterclockwise will give you more predictable note tracking on the divider with less sustain. The middle will have a small area where the gating opens and noise comes through. (Position may change when using a battery.) This is a good area to start and then slowly dial the knob away in either direction to find your sweet spot.

The Inducer Tube Distortion Effects Pedal Kit (LE) Featuring NOS 6189 Tube The Inducer is a Limited Edition tube distortion pedal kit designed around a New-Old-Stock 6189W JAN (Joint Army/Navy) Philips vacuum tube. This 6189 is a premium grade 12AU7 that was ruggedized for reliable operation in military mobile, shipboard, and aviation communications equipment, making it ideal for use in an effects pedal. This tube is characterized by reduced microphonics, excellent linearity, and long life. When driven hard, as it is in this Limited Edition pedal, it produces beefy distortion. The Inducer uses the same classic circuit as the MOD Persuader Kit, but the 6189 gives the Inducer rich distorted fuzz. There will only be 30 of these Limited Edition kits made and they are sure to go fast. Each has a hand designed box will be the envy of all your fellow musicians.

The Penetrator is a treble boost pedal kit with enough gain to cut straight through any mix. This pedal adds glistening harmonics that get loud enough to saturate your amp’s front end. Adjust the level knob to vary the output so there’s no mistaking when you kick this pedal in. Great for solos or when you need your guitar front and center.

Official demo of the MOD® Kits DIY Penetrator.

Build your own tube pre-amp pedal built around a 12AX7 tube. Go from clean, warm tone to smooth, real tube overdrive.

This kit includes pre-drilled die-cast aluminum enclosure and all parts with easy-to-follow instructions. All you need to provide is solder and soldering iron.

The Persuader allows for easy access to the tube, giving you the ability to quickly experiment with different tube brands and 12AX7 tube relatives.

Operates on a 9 volt battery or AC adapter, which is not included.

What people are saying about The Persuader:

"Great pedal and cool color! It makes a handy tube tester besides a real tube overdrive, you can get different gains and tones with an assortment of various tubes. Excellent and easy to follow instuctions with layout pictures, and you make it yourself!" "Very fun. Took me 5 hours to assemble, I've got almost no experience on the solder iron. It has got the good fuzz." "I really wanted a tube overdrive and this worked out great! It took me four hours, but it was well worth it, and the best part - is that I BUILT IT MYSELF!"

 

This is my third youtube video demo on the MODKitsDIY The Persuader Tube Drive. I can't stop playing this pedal and I have been experimenting with various types of preamp tubes and settled on the NOS RCA 12AU7 that I found at a local electronics surplus store.

The Persuader Deluxe utilizes a Darlington preamp to push cascaded triode vacuum tubes into distortion. Four dual triode vacuum tubes are included with each kit (JJ 5751, 12AX7B China, JJ 12AU7 and a NOS USA made 12AT7). Swap to create a wide range of tones from just a hint of break up from the JJ 5751 to over the top crunchy distortion using the NOS US made 12AT7. A boost switch provides an additional layer of flexibility with added gain and a little extra bottom end. An LED indicator lights up when the Persuader Deluxe is engaged and not in true bypass mode.

Clean-boost pedal kit with up to 38db gain The Piledriver measures 1.35" in height, 3.70" in width and 4.70" in length.

What people are saying about The Piledriver:

"If you're a pedal lover like me, who's always wanted to try their hand at building one, but have zero experience, then this is the pedal for you." "This is a good clean boost and was easy to assemble. Fun little project and I recommend it." "This kit was so easy to build and now it's my go to cut-through-the-bologna pedal. I use it at large jam session house parties. If there's some drunko playin' too loud, I stomp on this to cut through that bologna!"

In this video, we'll demonstrate the sounds that The Piledriver from MOD® Kits DIY is capable of producing. The Piledriver is a clean boost pedal kit with up to 38dB of gain.

Distortion pedal kit that has that 60s and 70s fuzz. The Rattler measures 1.35" in height, 3.70" in width and 4.70" in length.

What people are saying about The Rattler:

"If you've never built an effects pedal before, this is a good starting point. It is simple to assemble and has easy to follow instructions. This is a straight up basic fuzz pedal that you can use to kick out the jams." "This is a mean little fuzz pedal. The Rattler certainly packs a bite!" "This is the first effects pedal I have ever bought from these guys, and I will be buying more."

A second video on the MODKitsDIY Rattler Fuzz, but this time playing it through a Fender DRRI. The first video, a Marshall Class 5 was used. The Rattler's tone was much darker sounding on the Marshall Class 5 amp and much brighter on the Fender DRRI.

The Ring Resonator kit is an octave-up fuzz effect; an all analog design that captures those late 60s octave-up fuzz tones. Transformer-coupled germanium diodes produce sounds that range from a subtle octave up to thick, harmonically rich sonic textures and synth-like tones. Experimenting with different pickups and tone control settings on your guitar with the Ring Resonator can also produce sitar-like sounds.

The Ring Resonator Deluxe is like having two all analog pedals in one. It contains the octave-up fuzz effect of the original Ring Resonator with added LED, push-push output pot and mini-toggle switch. With the push-push output pot down, the octave-up effect is removed and fuzz-only is achieved. In the fuzz-only mode of operation the toggle switch allows you to switch between dark fuzz and bright fuzz tones.

The Rock Bottom is a bass fuzz kit that gives you all of the sizzle you’d expect from a vintage fuzz without sacrificing those low frequencies. Use the blend pot to set your fuzz levels and dial in the volume to get that sound you need. This versatile pedal can be used for the sludgiest bass tones to the cleanest boost and everything in-between.

The Saturator is an overdrive pedal kit that can cover a wide range of gain effects, transitioning smoothly from a massive clean boost to a warm and saturated distortion with the turn of a knob.

The saturation is controlled with the "Soak" knob, which dials in the amount of symmetrical soft-clipping applied to the guitar signal. When fully counterclockwise , the signal is unaffected and clean. Rotating the knob clockwise will incrementally increase the soft-clipping, morphing from a clean signal through subtle-to-heavy saturated overdrive sounds and straight into distortion territory. The "Level" knob sets the overall volume of the clean or saturated output. Unity gain is at roughly 8 o'clock. With the "Soak" set to clean, rotating the "Level" knob clockwise will increase the level to upwards of 30 dB.

The Step Ladder is a passive input attenuator using high quality components for excellent reliability. True-bypass mode provides the maximum signal level. The attenuator pot and two toggle switches allow for flexibility in the amount of signal attenuation when not in bypass mode. Treble bleed capacitors in the circuit retain crisp high frequencies even at maximum attenuation. The Step Ladder is ideal for anything from getting a slight boost while playing single-note acoustic guitar leads or for jumping from clean to overdrive in a high-gain electric guitar amp. The Step Ladder’s compact size (3 ¾” x 1 ½” x 1 ¼” enclosure) fits in most guitar cases. Its battery-free operation ensures that it’ll be ready to go whenever you need it.

The Suspended Chime has two powerful effects in one pedal - chorus and chorus/delay. The Suspended Chime features a blend knob which allows you to go from subtle to lush chorus effect in either set up. Using the selector switch, you can add a 190 millisecond delay to the chorus introducing special depth to your tone. Varying the dry/wet mix can fatten your rhythms or produce a shimmering 12-string sound. The Suspended Chime kit comes equipped with an LED indicator and industry standard 9 volt center negative power jack.

This is a guitar pedal that I built using the ModKitsDiy.com kit. It's called the TEA Philter and it produces a fixed wah tone that you can dial in. First attempt at assembling a guitar pedal and I'm pleased with the result.

The Thunderdrive is an overdrive pedal kit that will provide a signal boost at low gain settings and it's own distortion at maximum gain settings. You can use it to push your preamp into overdrive or as a source of smooth distortion. Using point to point wiring and easy to follow instructions you can have a working overdrive pedal in a matter of hours. All you need to provide is solder and a soldering iron. Uses 9 volt battery which is not included.

Adjusting volume control and gain controls provides a wide variety of tones in spite of it's simple construction. The Turbo switch provides an additional boost in volume and less internally generated distortion. The pre-painted black enclosure, red control knobs and red LED indicator give the Thunderdrive Deluxe an understated attractive finish. It is capable of overdriving the preamp section of your guitar amp or adding it's own layer of distortion at lower volume. The current draw of this pedal is very low at 1.3 milliamps, allowing for long battery life.

The Thunderdrive Deluxe LTD is an overdrive pedal kit that will provide a strong, clean signal boost in the early gain settings and smooth distortion at maximum gain settings. Adjusting "Output" and "Distortion" controls provides a wide variety of tones in spite of its simple construction. It is capable of overdriving the pre-amp section of your guitar amp or adding its own layer of distortion at lower volume. This version is equipped with a three-position diode-selector switch.

The switch offers three different settings and tones. The top position is the classic silicon clipping diodes used in the original Thunderdrive. The middle position gives you the lifted diode "turbo" sound from the Deluxe model. The bottom position is a new setting limited to this version using germanium diodes for a warm vintage distortion.

In this video, we'll demonstrate the sounds that The Thunderdrive Deluxe from MOD® Kits DIY is capable of producing. Adjusting volume control and gain controls provides a wide variety of tones in spite of it's simple construction.

Imagine a hand wired, USA made, point to point pedal for under $35, USD. Yup!

In this video, we'll demonstrate the sounds that The Trill from MOD® Kits DIY is capable of producing. This pedal is a classic tremolo effect.

The Trill Tremolo pedal offers classic tremolo tones in an easy-to-build kit. The Trill's "Speed" knob provides a wide range from a very slow to rapid-fire effect. The "Depth" knob varies the ratio between effected and dry signal.

Using modern, low-noise transistors makes operation of The Trill quiet with no signal drop when engaged. The Trill uses true-bypass footswitching so it is out of the signal path when not engaged.

All you need to provide is solder and tools! Uses 9 volt battery which is not included.

Please see our latest demonstration of The Trill Tremolo with much improved video and audio quality and some additional information about the kit:

Please check out The Verb Deluxe.

Reverb pedal kit based on Belton Digi-Log module. Bring reverb to your guitar rig with the Verb. Enclosure is 1.35" in height, 3.70" in width and 4.70" in length. We recommend a 9-volt adapter for use with this pedal.

What people are saying about The Verb:

"I didn't know that a digital reverb could sound so warm..." "Me and my son put this together on a Sunday afternoon. An easy build and sounds great!" "My amp has no reverb. I built this pedal and now it does!"

Built this MODKitsDIY The Verb reverb pedal and it sounds amazing.

The Verb Deluxe kit is built around the Belton Digi-Log Mini Module (P-RBTDR-2H-X) for a great digital reverb sound. The Belton Digi-Log module was built as a replacement for traditional spring reverberation units.

Features include both "Dwell" and Mix controls, allowing the dry signal to be blended with the processed signal - from just a hint of reverb to deep, cavernous echoes.

The "Dwell" control adds an extra flexibility, providing a full palette of sweet reverb sound. Warning: The Verb Deluxe does not hold back on reverberation potential. At maximum "Dwell" and "Mix" settings you may be overtaken by a virtual tidal wave of sonic reflections.

A short demo video the MODKitsDIY The Verb reverb pedal. It took me about four hours to build this pedal and was well worth it. Great sounding DIY reverb pedal.

The Wahtz Wah Pedal Kit produces the classic Wah tone you've come to expect with a hint of extra bite and growl. True bypass switching ensures no loss of signal when the Wah effect is not engaged; and the long life potentiometer manufactured specifically for use in Wah pedals is included to provide years of smooth, quiet operation. Point to point construction allows advanced kit builders to easily experiment with modifications to further tailor the tone to more individual tastes.

The Wave is a versatile stand-alone, tube-driven analog spring-reverb-unit kit. It can be used in front of your guitar amp or as a line-level analog reverb effect for the recording studio. Two controls allow you to serve up a wide range of wetness from just a touch to over the top psychedelia. The "Dwell" control adjusts the input signal level driving the tank and the "Reverb" control adjusts the level of output reverberations from the tank. The Wave’s all tube design utilizes four dual triode vacuum tubes - three 12AX7s and one 12AT7 - and comes with a MOD® three-spring reverb tank. MOD® reverb tanks are deemed the closest to the original reverb tanks from the '60s made today. The Wave’s reverb function can be switched in and out pop-free via the front panel toggle or with a foot switch (purchased separately).

The Wave has standard ¼ inch in-and-out guitar jacks in the front for use with your guitar and amp, and standard RCA in-and-out jacks in the back panel for use in a recording environment. The Wave is equipped to be rack mounted using just under 3U of space and is approximately 11 inches deep front to back. Four large rubber feet allow the Wave to be safely placed on top of most contemporary guitar amplifier heads and combos for stage use, and it fits into a rack without having to remove the feet.  The Wave comes with a pre-punched powder coated steel chassis, easy-to-follow instructions and all necessary parts.

For use in countries with a 240VAC mains, the Hammond 290WEX can be used in place of the included power transformer. The 290WEX cannot be substituted in the kit and will need to be purchased separately.

In this video, we'll demonstrate the sounds that The Wave from MOD® Kits DIY is capable of producing. This effect unit is a tube-driven analog spring reverb that's capable of serving up a wide range of wetness from subtle space to over-the-top psychedelia.

I'm really enjoying this pedal. Its has that raw and mean tone and can clean up sparkling shimmer. Modkitsdiy really did a great job in designing this pedal and a fun build to do.

Kurt Prange builds the Thunderdrive Deluxe pedal kit from ModKitsDiy. The music that plays in the background was actually recorded using the same completed pedal that you see being assembled in the video. The kit took about 1 hour to finish putting together.

This is a brief overview and demo of the Thunderdrive Pedal kit from modkitsdiy.com.

Been very impressed by the quality and tone the pedals I've ordered from MODKitsDIY. My latest MODKitsDIY pedal builds are the Thunderdrive standard and deluxe (black casing).

Shape your sound with the Tone Attack. 12 o'clock settings give an approximate unity gain with the pedal. Rotate the treble or bass knob counterclockwise to cut the corresponding frequencies. Rotate these same knobs clockwise to boost the frequency bands. The master boost knob can be used to attenuate your signal or push your tone to screaming loud volumes.

Any of the kits rated a “1” in our build difficulty ratings would be a good beginner kit. The Piledriver’s larger enclosure makes it perfect for a beginner.

See our guide to build difficulty for a list of each kit and its challenge level.

These kits use 22 AWG wire.

For kits which do not have a built-in power jack, a 9 volt battery is required. If you do not want to use a battery, we have instructions for adding a DC power jack for many of our kits in their File Downloads section. 

All you need to provide are common hand tools, a soldering iron and solder. Everything else is included, including a pre-drilled enclosure

Many of our kits can be built with a soldering iron, solder, and very basic tools (screwdriver, pliers, wire strippers). However, in order to prepare for any build issues, we recommend having the following:

  • Wire Strippers
  • Needle Nose Pliers
  • Cutting Pliers
  • Desoldering Pump
  • Solder (60/40 rosin core recommended)
  • Soldering Station
  • Phillips Head Screwdrivers
  • Slotted tip screwdrivers (3mm tip)
  • Digital Multimeter (DMM)
  • Alligator Clip Test Leads (to fit DMM)
  • Channellock Pliers (or similar type)
  • Miniature Round File (fine cut)

For the pedals that have a power jack, a standard 9VDC, center pin negative power supply should be used.

We recommend the use of regular leaded 60/40 solder. It melts at a lower temperature than lead-free solder, so it's less likely to cause a cold solder joint or damage components.

Our kits utilize point-to-point wiring using terminal strips rather than a circuit board. This is done to make a step-by-step build easier and to help the builder learn the circuit's signal path and open up the possibilities for modding. Point-to-point wiring requires a slightly larger enclosure.

MOD Kits are intended to introduce people of all skill levels to building, modding, and repairing gear. We find point-to-point wiring to be friendliest for beginners and also encourages modding more than a set PC board layout.
