Hey guys. I've got a slight problem, here it is: I've got a Marshall DSL 100 through which I'm running a lot of effects. The problem child of the bunch (i believe) is the Keeley modded Boss SD-1, which drives the front end. I have a noise suppressor on it that also runs into the front end instead of in the effects loop. Now, placing my one and only noise suppressor (a Boss NS-1) removes it from cutting the hum down in the loop, and consequently I have major hum when I don't play. Now, I know this isn't due to the distance because I've stood about 8 feet from the amp and I still get hum. The SD-1 creates such a great amount of feedback without the NS-1 engaged that it would be insane not to run it without it. I'm thinking I should buy a second noise suppressor. Is there a affordable and effective option that won't suck tone that could possibly eliminate the hum in the loop and feedback from the SD-1 driving the front end?
