So my band's beginning to become a lot more acoustic and I've been struggling to be heard. Right now I'm using a Kala U-Bass and I honestly can't even hear myself when everyone else chips in. I like the U-Bass for traveling and practice, but it honestly can't stand up against everyone else. I know most people suggest simply plugging in and playing, though where we practice acoustically there is absolutely no access to power and I'm not keen on constantly buying batteries (I have a battery powered Yamaha combo amp but playing by bass just drowns the batteries out in two days of practice) So this finally brings me to my question, what do you guys recommend for an unplugged bass that can be heard over everyone else? I've seen some resonators but there's a much larger selection of acoustics. Give me your thoughts.
