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.

Fuzzhead FX MOuSeFET

Here is a variation on the Rat theme. I wanted to do a MOSFET Rat since I have a few CA3240 dual op amps lying araound and I like the sound of MOSFET transistors of hard clippers. Caps is enlarged a bit for a bit more low end and a switch for a 10uF running in parallel with 2,2uf cap is added for a bit more gain and low end. Stock output FET buffer is replaced with the second half of the op amp.

One modification is done; a transistor gyrator (Q4) replaces stock op amp gyrator due to board space.

Mesa Boogie 5 Band Gyrator Eq

A DIY adaption of a Mesa Boogie 5 band eq found in many Mesa Boogie amps. Original tonestack has inductors but is is changed to  op amp gyrators. This design was created by Cameron (thanks!) and layouts is verified by AlexS(thanks again, mate!)

Revv G2 Pedal

 Shares the same footprint as G4 pedal but some component values is tweaked for less gain and slightly different overall eq.
