Hi everyone, I play guitar and want to start learning bass soon. My budget for the new rig is limited, so my amp will need to be a relatively modest combo. For the most part, I'll need it just for practicing alone and playing along with CD's, maybe jamming a bit with some friends once I get up to speed, but not an actual band or performance situation. What sort of wattage should I be looking at? At the lower end of the spectrum, is it going to make much of a difference between 60 and 100W? Also, any particular brands/models to look for under $300 new? Thanks.
