I've been thinking about building a rack and using my current amp. I need to put a noise suppessor and a maximizer in with it. An EQ and a tuner would be nice too... but that's not as important. Where's a good place to look for racks, and all the parts that are rack mountable? Is there a multi-fx unit that is rack mountable and can do all that well? I don't want to spend an insane amount of money either. Thanks.
