I've been playing around with my rig to see if I can lower my background noise. I've put some EMG's in a guitar with some decent results and will probably buy another set soon, but I don't think that is the solution to the noise (i'm not really objecting to 60hz hum from the pickups as much as the hiss from the pedals). I have a Fulltone '70 (Prefer the Silicon fuzz tone, but is a little noisy) and a Frantone Sweet (this is the really noisy one). I can get along with the '70 if I'm using high impedance, but I know it does not like anything low impedance. Is there a Fuzz (or a fix for my '70) that sounds ok with low impedance and high impedance guitars? Thanks.
