Pretty sure last time I looked it was a 3 transistor circuit, will need to dig through some boxes to find out if I still have one, but it has been the one that I missed most when I moved away from physical pedals. The Bender model doesn't have the insane out of control bass and high mid harshness. I have EQ'd to try to replicate, but never really got the same look of shock and awe from bandmates and audience as when I hit the nuclear button on the Supa Tonebender. I still have a mid 90's Russian Big Muff Pi, and I think that must be more after the Triangle than the Ram's Head (which I never tried). Massive and smooth, but never aggressive or harsh enough to make me laugh like when using a Supa Tone Bender. It's not a nice sound, but can be a very good one.

Interesting! I haven't seen a 3-transistor Colorsound Supa before. Does yours look like this one (https://www.coda-effects.com/2015/10/vintage-colorsound-supa-tonebender-1973.html)?
I have a big red JEN Jumbo Fuzz from '73 that elicits the same reaction. It's just a massive sounding fuzzbox. It's based on the V1 Big Muff, though.
