Death by Audio White Card Fuzz

Now verified. But as with DBA Octave Clang I felt it was lacking in gain. But there is a super simple mod to increase the gain of the LM386 amp. Just omit the cut between pin 1 and pin 8. Now we have both a fat fuzz or way over the top octave fuzz with the gain control dimed. Back it of for sitar tones or overdrive.

Layout with gain boost mod.

Maxon OD 820

Slightly modified power section and a protection diode for the charge pump.

BAJA BE100 Overdrive

Based on the frequency response of Friedman BE100 amplifier. Added the tonestack at the end of the circuit.
Schematic and info HERE

Fuzzhead Fx Foghead

YAFF (Yet Another Fuzz Face) with some addons. After the fuzz section there is a J FET buffer before the tonestack to keep things clear. Tonestack is inspired by Death by Audio Fuzz War V2 but with a bit more focus on the mids. A ge diode acts as a clipper on the treble side which adds some compression and sizzle.

J Rockett Hightop Boost



The 2N708's isn't that common but any low gain NPN silicon should work like 2N2369 or 2N1613. Try hfe in the 50-100 ballpark.

Seymour Duncan Pickup Booster



 


As you can see there is lots of odd resistor values so here is a layout with closest more common values.

Fancy Lime Gorn Overdrive.

A good sounding low gain/medium gain overdrive (depending on pickups used) with a interesting diode clipping setup and a useful "Woody/Tinny" switch. More info and schematic HERE.

Earthquaker Devices Black Ash Endangered Fuzz

Traced by cenotapf and AlexS. It's basically a silicon Tonbender Mk 2 with a quite subtle treble cut control. 2N3903 transistor is a low gain version of 2N3904 so any NPN silicon with Hfe 100-150 works like MPSA06, PN22222, 2N2369 etc.
