The Analogman Astro Tone fuzz is somewhere between a fuzz and distortion, it acts differently into different amps. But it sounds great into almost anything!
This pedal is based on the 1960's SAM ASH FUZZZ BOXX and ASTROTONE FUZZ made in New York City in 1966-68 by the Astro Amp company. It was one of the earliest and best fuzz pedals. This was the first pedal that Analog Mike cloned, way back in about 1994.
The sound is not as compressed as a Fuzz Face, not SUPER thick and saturated, something between a fuzz and distortion. It's fuzzier into a smaller amp (Fender Deluxe), and more of a booster into a large distorted amp (Marshall 1970s Super Lead). It can also be stacked with other pedals, for example running a fuzz face into it can get a sound like Spirit in the Sky, which buzzes and cuts out. Or run the Astro Tone into an OD pedal like a TS808 or KoT to make it fatter.
