Hi guys,i've got a fuzz factory pedal. It plays well on my peavy 65 watt studio 112 amp as well as the marshall 30 watts amp at olando studio. However, whenever i go for gigs with those marshall stack amps,the sound tends to be extremely thin and trebly as opposed to the normally thick and fuzzy tone,and i've turned up the bass already. Whats wrong? Do i need a noise supressor? what can i do to beef up the tone?
