  1. Verified. Sounds really good. Tried J201 and 5457 but ended up using J113. Seemed to give it more gain to me. Great fuzz sound maxed out that cleans up well. Really appreciate everything you’re doing. Thanks!

  3. Im not sure i need another overdrive but I'm impressed with the symmetry of the layout. I may give this one a try this weekend. Nice work!

  5. @Chris Thank you for your help. You can tag this verified. I used J201s biased at 4.5v each. Used a 250K trimpot for one of the trims. Worked fine. Gain adds lots of volume and fizz. Sounds like a direct-into-the-board fuzz. I used linear pots for gain and tone. Makes a great preamp. I like it best with gain very low and volume up. Glad I built this one. Gonna try J113s next and maybe lower the bias a tad.

    Thanks for the drawing fuzzhead!
