WTF Big Enuff? - Violet EditionVerified
Based on the WTF Big Enuff? - Violet Edition
From the post
Another distortion unit designed by Pedro (WTFiCanBuildMyOwnPedals). Here is his own words on his creation.
"This one will destroy many amps and eardrums. It is nothing new, just a marriage between a Big Muff and the Booster from the FZ-2 (pedalPCB's version) which has a very powerful EQ... and it sounds exactly like I imagined it. Anders was very helpful, as always, in putting a layout together when this came in conversation and after some developing here it is. Earlier versions had less pots and was just a fuzz, but this is the ultimate version in my opinion: no need to waste a perfectly good booster and why not have lots of controls to shape the texture of the fuzz?
The DPDT switch (which I like to have on a footswitch) activates or bypasses the three gain stages of the BMP (LEVEL, GAIN) before hitting the booster (MASTER; BOOST, HIGH, LOW). Everything interacts pretty much with everything to create diverse and loud textures of fuzz with crazy sustain. This one is loosely based on a Violet Ram's Head, which is one of my favourite Muffs, but every version should work (a Russian version for bass was also built and sounds great)."
