I searched around the forum to see if I could get an answer to this question but found nothing specifically geared to Big Bands and URB. I have some smaller amps that work great with smaller combos (a Polytone with a 15' speaker and an AI Contra). However, I need something with more power/loudness without feeding back for playing with a Big Band. I also want something lightweight as I can't carry around a huge/heavy rig anymore. My budget is fairly tight too -- I have less than $1,000 to spend. I was looking at the GK MB 212 but would anyone else have any suggestions? Thanks!!
