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?

We don't have any Germanium transistors on hand to test it but I would think with the right transistor this could be accomplished with little to no changes.

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!
