Right now I'm playing six string basses exclusively (though I'm hoping to get a four in the near future), and I'm not too thrilled with the sound my Acoustic B30 is putting out. I'm wanting to get a new amp in the near future and I was hoping for some advice. First of all, I live in a one bedroom apartment t on the second floor, so something light and portable is a definite plus. I would very much like to have headphones and an aux in for play along tracks. I'm currently a bedroom warrior with the occasional visit to a friends house to jam, so I don't need a whole lot of power, and in fact I would prefer something that sounds good at low volume levels. I'm hoping to stay under $400 if possible. Id also be willing to consider a travel amp in addition to a practice amp if I can find them at the right price.
