Thinking about picking up another bass, I have a G&L Asat and love it. I am considering a SB-2.Now the question I have is they don't a have tone control knob and not sure if I like that. I know you can turn down the bridge pickup for more bass and the other way around for more treble but how much effect does that have on the volume ? I'd like to be able to change the tone without losing any volume. Any input would be great and for you guys with SB-2's tell me a little about them Pro's vs Cons..Thanks guys..
