The Penetrator

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.

If I purchased an NPN Ge transistor with biasing resistors from small bear (for example) could I use them in place of the supplied Si transistor and biasing resistors without further modification?

Actually this circuit wasnt designed to use a GE Transistor. Its actually a modified version of the Brian May Fryer Treble Booster. The original circuit was designed as an "upgrade" to the Rangemaster. It swapped GE for SI and added a couple resistors and Caps in to filter some of the noise and upgraded the GE transistor to a more modern silicone one. To get a GE transistor to work you will need to make two changes. The 8.2K collector resistor and the 100K resistor will need to be changed. I can not tell you what the values should be as literally they will be different for every single GE transistor you use. So if you really want the GE to work then I suggest breadboard the circuit from the schematic and add a 250K Pot in place of the 100K resistor and a 10K pot inplace of the 8.2K resistor. Then adjust the two pots until the sound is biased and sounds the best to your ears. Then unplug the pots and use a multi meter to measure the resistance you dialed in on the pots. This will give you the value of the resistors you need to get the GE to work.
Hi! Can you guy's provide us a demo with this pedal behind the ThunderDrive? Also playing rhythm? Treble boosters sound best when they are pushing Overdrives. Thanks!

I built this pedal, and it works BUT there's an unpleasant and unwanted squealing that occurs as the effect kicks in and increases along with the level. What should I be looking for to fix that? Thanks!

On the Instruction cover it shows "To Amp IN" on the left side of the pedal and "From Guitar OUT" on the right, normally the guitar input in "IN" and the pedal to the amp is "OUT". Drawings 1, 2, 3 & 4 at the end of the instructions are looking with pedal turned over (I assume) so the Guitar input is now shown as "Input Jack" and the "Output jack" is to the amp. Is this correct? It's a bit confusing. Also, the Input jack is stereo, does that mean a stereo guitar cable must be used? Sorry if this is a stupid question. Thanks!

Yes that is correct. The guitar plugs into the input jack and the output jack goes to the amp or the next pedal. A stereo cable should not be used. You'll need a standard mono guitar cable. Stereo jacks are used in battery powered pedals so that the battery is only in use when a cable is plugged in. The negative terminal of the battery is tied to the ring lug and when a standard mono cable is plugged in, the ring is then shorted to the grounded sleeve allowing the battery to operate.
