Ok so this is the sound of a big muff that has been modded - moderately - but certainly modded
The biggest tone indicator here is the LEDs for clipping diodes AND there are only two - I completely removed the first pair of diodes (ala a tonebender)
The other changes are the clipping stage uses a BC184 tranny (lower hfe than stock, smoother) and the stage before the clipping stage uses one as well. I changed some resistors to lower gain overall but I kept the final tranny stage which really makes the muff - well sound like a muff.
The tone control uses values of my own so there is substantially more bass.
I'll be more than happy to detail this mod in full when I get a chance to go back and take note of everything I did.
My goal: to make a nice tight almost OD/ Distortion sounding fuzz for players that like to get busy.
I highly recommend you pull the first pair of clipping diodes and change the second pair to LEDs if you want to really tighten up your muff.
this may appeal to some - while others may hate how the muff loses its "all consuming" nature.
here's the clip (it's a craptastic recording as the cord is kind of screwed up so that's the scratching you hear - not the pedal.)
