Over the past few weeks, I've been trying to think of a method to get my ideal overdrive tone, and what I came up with involves taking two (or possibly more) signals, and blending them together. To accomplish this, I'd like to buy a rackmount mixer, but I don't know which will suit my needs. Mainly I'm looking for something with 1/4" inputs for at least 3 channels on the back, individual volume knobs for each channel on the front (as well as a master volume), and a mono 1/4" output that sends the final mixed signal... Are there any mixers that fit my description? I don't really want to spend over $200 unless absolutely necessary... in fact I'd prefer to spend less than that if possible. But I'd like to avoid Behringer... just a personal choice. Got any suggestions?
