There's a bunch of different Big Muffs out there... here's a fun one. This one here is a V7 second edition, colloquially called a Black Russian, four screw box, made in Russia 1999-2000. These are the exact same circuit as the last of the bubble font green box units, which fetch enormous cash these days. This one is in tidy shape, although the feet and battery cover are missing. It sounds enormous: thick and swampy with singing sustain and harmonics as rich as your Tesla driving uncle. Tip: this is unlikely to be worth less in a few years, if you catch my drift.
