What is a decent cambo amp for somewhere between $500- $700? I don't quite need a big ole stack. I want a big 4x10 with a 1x15, and a 450 watt head, but that ain't gonna happen. So, a 2x10 combo would be a nice settlement. Basically anything would be an upgrade from my Fender Frontman B15. I've played through a Gallien- Krueger 400RB/210 240watt combo, sells for about $750. It is a little more than what I want to spend, but something along that line would be great. What is recommended?
