Does anyone out there use a rack mounted compressor Just for their bass? The Sound system we have to use when we play at our gig has one 2 channel compressor and the sound man has all the vocals in channel one, and the bass Drum michrophone in channel two. I'd always heard that bass needed compression. I bought a DBX 266XL, but I know very little about compressors and I don't really see that it is doing all that much for me, except add a noticeable amount of white noise to my signal. What should I do. Lose the compressor, cause I dont need it? Learn how to hook it up right, what? Did I just waste 150 dollars.
