In discussing the fuzztone sound for guitars and basses, a lot of claims are made by fans about how it all began. Everybody knows Keith Richards' used it on the Rolling Stones' "(I Can't Get No) Satisfaction. And of course Paul McCartney played "fuzz bass," using the same or similar tone-altering device as Keith, on tune "Think For Yourself" on Rubber Soul. As noted so often on this blog, for various reasons, the truth is often not that simple. I'll try to put it in a coherent order.
