A friend of ours has a vintage Acetone Fuzzmaster. My father copied and made several versions it, and was researching different versions. This is one that he selected the parts for, and that I built into a holiday canister. I didn’t have quite enough room for a switch, and I wanted to keep the artwork intact anyway.
The form factor is perhaps not ideal, and the knobs on the sides are difficult to read. Works nicely as a “set and forget” type effect as part of my electro rig.
