Totally agree with a modeling amp I reccomend simple simple. My first amp for guitar was the VOX DA5 around a hundered bucks simple simple. Has an aux input in the back you can plug a mp3 with backing track on it and your set. Aux is strait thru no effects on the aux. But much to do with simple on the amps modeling controls. Vox also has a tone room for help with setting s to differents songs and artists.
