As the title suggests .. I have a B2.1u, which I have been using for increasingly limited functions since switching to a more separate pedal type setup. Unfortunately, I have a couple of pedals with some really bad noise and feedback issues that I am trying to fix. I was going to buy a Noise Gate (probably an NS-2).. but then I remembered that the B2.1u has the ZNR Noise Reduction feature on it, and wondered if anyone has any experience using this to suppress noise from external pedals? My thinking is that I would need to put it at the end of the chain, but the pedals themselves don't get noisy until there is a bass signal going into them (if I switch off or turn the volume down, the feedback goes away), so maybe I could keep the Zoom right after my bass? Any opinions or advice would be good. I won't have a chance to try it out until I jam with my band tomorrow night.
