Great old school green big muff fuzz sound in a smaller box. It can get raucous or just warm and fuzzy. A previous owner painted it with what appears to be model paint, but a hammer and sickle is always cool. The build quality is quite good, and it has some unique knobs. Hand numbered, initialed and signed FWIW. I'm guessing it's a fellow TB'er but I can't say for sure.

To give an idea of the sound, I have a clip below of me noodling on a 75 p bass through an MB200 direct into Garageband. I mostly just change up the sustain and tone settings and keep the volume at noon, but there's one part toward the end where I dipped the volume knob thinking the next tone setting was going to be searingly loud.
