I started playing electric guitar in 1965, and got one of the early Maestro FZ-1 FuzzTone pedals. Used it for years until in 1970 or so I traded up to an Ampeg Scrambler, and while I still have (and use) that Scrambler, the FuzzTone is long gone. Now that unit is considered a classic, of course, but at the time it felt somewhat limited in range.
I'd think about getting a used FZ-1 just to have one, but I've got like six great overdrive / distortion pedals (Scrambler, FuzzFace, TS-9, Octavia, TubeDriver, etc.) and really don't need more at the moment.
