I have just set up my effects chain and its goes like this.. Q-tron+ > Aphex Punch Factory> Sansamp> Double Muff(distortion)> Aphex Bass Xciter>Digitech Bass chorus I certainly like my setup, but my problem is with the double muff. When it is activated, there is a terrible amount of unwanted noise/hiss that goes out the amp. As I turn up the muffs, the noise/hiss gets louder and bigger. I tried turning down the treble and it still hissy. I have a Fender Rumble 100 combo, and I know its not the best amp but I'm sure the amp is not the main problem cuz the hiss comes only when the double muff is activated and especially with other pedals. I'm sure the problem is not cuz of my double muff itself cuz I think most distortion pedals give off a lot of hiss and unwanted noise when on. WOULD A NOISE SUPRESSOR PEDAL FIX THIS PROBLEM? I've been eyeing the Boss NS-2 Noise Suppressor. do you know anything about the boss? if i should get the suppressor where should it be in the chain?
