Well, I use a BOSS NS-2 Noise Suppressor on the highest settings available to eliminate noise from my rig (2 Channel Dual Rec). I actually have 2 OD pedals I use. I use a Maxon OD808 for my heavy rhythms, on at all times...and then I have a Maxon OD9 I'll kick on in addition for leads for sustain. Even with the NS-2 on max settings, using the OD9 basically gives me infinite sustain if I want. I could literally hold a note until my fingers got tired, and the NS-2 still kills all the noise in the rig. I tested that theory the other day to see how much sustain it would give and after a while, our vocalist came in from his smoke break and said "Is that ever going to stop? It sounds like you're trying to summon the devil in here or something"... :lol:
