  1. Verified! I flipped the 25u electrolytic and made an NPN version with GT404s.

    2. I think it sounds pretty good, I will definitely box it. I had to swap out the 6.8k resistor with a 13.3 teepee to get the Q2 voltage closer to 4.5v. I'm curious if there are any transistors similar to the SFT352 to try, haven't seen those available anywhere. I put in some MP38As which also sounded good, maybe little more compressed. Thanks for the layout!

    3. This was very treble-focused so I ended up removing the 47k between Level 3 and Level 1, which brought back a lot of missing low end. With the Attack and guitar volume all the way up it's very heavy fuzz but rolling the guitar volume down a little cleans up just enough and now has a good balance between treble and bass. Definitely worth a build!
