Dwarfcraft Great Destroyer

Here's a fun sputtery beast for Fuzz Friday. Like many of Dwarfcraft offerings, this ones got a lot of character and goes from fuzz to experimental with just a few knob turns. I've laid it out so you can fit it in a 1590B long-ways (much like a zVex pedal). Here's the schematic for reference.

  1. Built this one up and it worked great via toner transfer. Tested it at different DC voltages and worked well down to 3 volts.

    I haven't plugged a guitar into it yet but i liked the way it made my synth sound - check this one as verified.

    Interesting self oscillation mod if you connect a pot between pin 2 of the drive knob and pin 2 of the "tone" (lol) knob - makes some good noise.

    1. The UBE is the unbuffered version and this one needs the buffered 4049.

  4. Fixed one of these for a friend a few years ago but he had a gig the same day so i never got to play around with it. Couple questions.... Just wondering the 100uf filter cap, was that something in a new schematic or did you add that? if so just curious. Second, maybe this is a new version but i remember the original having 1uf caps (electro) in place of the 100nfs Probably negative side going facing the in and out pads. Just food for thought. just found a 4049 (unbuffered)in my bin but ill try it out for grins with 1ufs and and report back.

    1. Just going off the schematic that's online. The power filter cap is just good building practice IMHO. I add it and polarity protection to everything. Let me know how it goes!
