noticed this the other day. if i roll the guitar tone off all the way, my NOC3 BC108 fuzz sounds downright nasty and filthy. this is a good thing, mind you i'm just curious as to the, well, i guess physics behind it. could there be some sort of phase cancellation going on when tone is all the way up? even though it's nastier, it's still clear. doesn't sound 'dull' in anyway. thoughts, answers, theories?
