Ok, I going to start playing live again after 3+ years of recording/producing/studying. It has been quite productive and I now play 10 times better than before, got a better a bass which is set up perfectly for my playing. Now I want to get a bass amp. I thought I didn't want a combo, but some of the new combos sound quite good. I can get my sound from any half decent bass amp expensive or cheap. I will play with many different people and many styles but just backing up, nothing fancy. A Nathan East kind of sound. so what to look for. 1) features like, fx loop, speaker out, xlr 2) portability 3) reputaion 4) volume What other things should I look for?
