THORPY FX: Fallout Cloud (Muffroom Cloud)

THORPY Fallout Cloud Vero Layout v2a a1a7785c5a2e

The Thorpy FX Fallout Cloud AKA the Muffroom Cloud, is a Big Muff with a Baxandall tone stack. Here’s the thread on Freestompboxes.  It’s a lower gain muff, probably more like a BMP from the former Soviet Union, as they also tend to have 47n caps on the diodes and large emitter resistors.

ELK: Super Fuzz Sustainar

Another variation on the Big Muff, the Elk Super Fuzz Sustainar from the early seventies – one of the earliest Japanese copies known.  The Elk Super Fuzz Sustainar originally used PNP transistors, which is completely unnecessary now, given the availability of good NPN transistors.  The tone section is slightly different from a regular Big Muff, and retains more high-end across … Read more

The Hoof Fuzz – a great variation of the venerable Big Muff from Earthquaker Devices.  I think this was the one that really put Earthquaker Devices on the map back in the day.  The Cloven Hoof is very similar, but without the germanium transistors. What really helps these is the mid-shift pot.  Being able to flatten … Read more

ELECTRO-HARMONIX: Version 2, Ram’s Head Big Muff, 1973 #3, Point to Point Layout

EHX BMP 73 P2P 1572f22f24b6

I think this is my favourite Electro-Harmonix Big Muff.  I built this using vintage 2N3565 glob top resistors and opted for some large vintage ceramic capacitors where possible (mainly for looks). Sounds great – the lower gain vintage transistors do change the tone and feel to some degree.  Of course it still sounds like a Big … Read more
