So, I'm a fuzz neophyte of sorts. I've settled on some overdrives, and have now come to the realization that alot of sounds I like come from fuzz tones too. I have(Well I think I do) a pretty basic knowledge of what a Muff Fuzz is, a Fuzz Face, Germanium v. Silicon, pro's and con's of fuzzes in general. But what are the differences between MKI and MKII Tonebenders? I think the MKI's are often associated with Led Zeppelin I & II, so I have a basic idea of the sound, but what makes it different than the MKII? Thanks for enlightening me, if you can.
