Jen HF Modulator / Gretsch Playboy

Now get your irons out and build it. Place your favourite fuzz in front of it and get ready for some psychedelic brain melting action. The circuit is the same in both, Jen HF Modulator and Gretsch Playboy. For this layout, i've once again swapped the transistor pinout to match your everyday devices. Original has 2N5172 general amplifier transistors in it, but 2N5088, 2N3904 and many others are very close to those in their specs. If you want to use the original ones, just mind the pinout. I've also added series polarity protection diode and pulldown resistors for in and out to prevent your circuit from popping when switched on and off.

Here's a little dcemo clip of my build:
