I was wanting a compressor for yonks as I thought it would help my sound. I got a couple to try (borrowed) & was VERY disappointed.
I had the same probs with it raising my noise floor up so when I didn't play, you got all the buzzes & things.
If I put it before my Moogers it either had no effect (not even a phattening one) or it meant NO dynamics & things sounded pants.
BTW, I get a brilliant Phat dub sound with the moogers & the exp pedal can be used to great effect, not a bad sound for a rock band
