I could also use one. I just hooked up a (approx.) 20 year old reciever/amp to my jukebox (in early stages) and the sound isn't very good. I would like to play with the mid range a bit instead of sliding the bass up or down, and treble up and down. Hopefully there is a good one out there that a forum member knows about. The only ones I find while looking are full programs that play the music as well.
