Been playing bass for 2 years & gigging for past 10 months. Still a novice but getting there . I'm using a hartke 3500 and love it. We play blues/rock music ( cream, zz top , Rory Gallagher Etc etc). I want to know what graphic setting gives the best punch as I feel I'm not getting the sound I'm looking for. Any hartke forums I've read seem to say this sound should be easily got using 3500 top with 4x10 cab. Any thoughts?
