Fuzzhead Fx Mammoth Bender

I've always loved Tonebender Mk2's but always felt that it lacked some low end for the music I'm playing at the moment. So I decided to a heavy TB2 variant....no wait, it's more like this; What if an old Marshall Supa Fuzz met a Wooly Mammoth and had a baby?

It would be the Mammoth Bender. The core is a Tonebender Mk2 with some tweaked resistor values. Capacitor values and the tonestack is lifted from ZVex Wooly Mammoth. Transistors is NPN Germaniums, part number isn't that important more attention should be noted to Hfe and leakage which is noted bellow the layout.

This one is verified.

BBE 427 Distortion

By looking at the schematic it appears that this one is a mix of a couple classic distortion circuits....the core is a Marshall Guvnor with LED clipping with a tonestack lifted from Boss DS1. 2,15k reistor can be subbed for 2,2k and that huge 1000uf power filter cap could be subbed for 100uF.
