I have a Marshall AVT-150 Head and Cab. I love the tone, but at high gain levels there is alot of hum and hiss. I bought a Hush Super C Noise Gate to try and fix this problem. From what I read about what other people did to fix this problem, they ran a noise gate through the effects loop. I tried this and nothing, not even a small amount of the noise removed. I don't know jack about technical stuff and evidentally I'm doing something wrong. My effect loop is parallel if this helps. Can somebody give me a simple walk through of how I should hoop this thing up. Thanks!
