I just received my Keeley modded Boss SD-1. Really awesome sustain and boost for a great distorted lead sound. It really rocks. ONE RATHER LARGE PROBLEM!!! It causes a TON of feedback when it's not being played. I have a Boss Noise Surpressor running in the effects loop, but of course, the SD-1 is going into the input of the amp...so, what can i do to rectify this problem. I love the tone of the SD-1 5 star, but damn can it get awfully painful (especially for those without EARPLUGS!!! :twisted: :lol: ) to listen to the feedback when I take my hands off the strings! I know this is a simple problem that has a solution, but I'm too dumb to figure it out :lol:
