Hi, I'm looking to get a new bass amp (have a fender rumble 150 right now). I play about 4-5 gigs a month in bars and want to upgrade my rig. We play rock/heavy rock and I have a Stingray bass. Two of the most interesting choices right now for me seem to be the Hartke LH series with the hydrive cabs or the Ampeg Portaflex series. Anyone has played both and would like to share some advices?
