I've found that when you turn the volume up on every level for the Boss GE-7 (every frequency as well as just the volume), you can get a very fuzzy distortion. However, the volume is increased much more compared to being on clean. Is there a way to keep this distortion without the volume drop when I go back to clean? Would a compressor help?
A compressor would probably tame it as long as the fuzz is coming from the pedal itself and not your amp being driven really hard.

Just buying a fuzz pedal would honestly probably be a better choice, though.

I already have a fuzz, a bigmuff pi, but I prefer the GE-7 much more. I can get the fuzz at pretty low volume, so yeah, it's the pedal. Is there anything I can use?
get a clean boost that you can turn below unity gain, and put that after the eq.

or get a volume box like this: http://www.ebay.com.au/itm/VOLUME-BOX-GUITAR-AMPLIFIER-ATTENUATOR-ENGL-AMPS-/200621051072?pt=LH_DefaultDomain_0&hash=item2eb5f24cc0#ht_1194wt_907

and before you ask, no that is not an attenuator. it is a volume box.
