Noise suppressor squeal?
so i was at band practice and planned on using my boss noise supressor and ibanez analog delay in the loop of my 5150, and i got a huge amount of squeal (with my d-sonic re-potted). I tried the noise supressor before the amp and my setup still squealed, which led me to try the guitar straight to the amp with the delay in the loop and no NS at all...perfectly FINE, and hardly any feedback issues. Why would a noise suppressor create noise? any thoughts?
