Hendrix has some good examples of fuzz. I'm going to create a fuzz examples thread. Some early Zeppelin might require this type of clipping. Fuzz is a distortion box with boosted bass before clipping. Distortion is a tonally balanced clipping, with the eq carefully shaped before the first clipping stage, between the stages, and after the clipping stages.
Distortion sounds best before an all-tube amp pushing a real guitar speaker.
This is the type of sound you can hear all over Van Halen 1. Awesome 1996 article about preamp distortion history. I'm getting into preamp distortion and will provide more coverage of preamp distortion products. To compare two EQs, put them both between EQs and ask, which dist box supports a wider, better, more musical range of distortion sounds when used this way. You might have a great potential dist box that just happens to be presented with less than ideal pre or post Eq.
