The Atom Fuzz Drive is a simple yet effective drive circuit that was originally designed by Dan Coggins of Lovetone and Dinosaural as a DIY project for Electronics Today Magazine. It is based on the Fuzztone, a DIY project from a British magazine called Electronics Today International (ETI) in their May 1993 issue.

The Fuzztone circuit uses diodes in the feedback loop of an op-amp to generate clipping, similar to a Tube Screamer. This gives it more of an overdrive sound rather than a traditional fuzz sound. The tone control is a “balance” type, similar to the Big Muff, allowing for tonal shaping.

Interestingly, the Fuzztone bears a strong resemblance to the Yamaha OD-10MII, an obscure overdrive pedal from 1987. While they sound different due to component selection, the structure of the schematic is very similar. It is unclear whether Dan was aware of the OD-10MII or if it influenced his design of the Fuzztone.

The Atom Fuzz Drive is a direct adaptation of the Fuzztone circuit based on the schematic from the article in ETI. It was never released as a commercial product, but it remains a popular DIY project for guitarists looking for a versatile and unique drive pedal.
