Could I just get some audio potentiometers from Radio Shack and wire them in all the same? I can get four of the those for about $12-14 then I can just make a plate to mount them in with some acrylic panels I have lying around. I guess thats more what I'm looking for (money is tight), then again the amazon link is pretty awesome I'd just have to find a place for it under my bar. I should have made my initial post more clear that I was looking at potentiometers, sorry about that. The second link is what I'm looking for I think, but I guess cheaper (I'm a cheapskate)!
