so here's my rig, i got a Ampeg B2R head, Ampeg 410HLF, Squier PB&J bass and i usually use a sansamp bass driver, so when im playing live i don't feel that bass and get told to turn up the bass,i only feel it when im very close to the cab, ive heard many times that the 410HLF can reach extremely low frequencies and have tried many different ampeg heads on it but i simply do not feel that thump and boom! is the cab or the head?? i just want my vocal chords vibrating when i play that low E, what cabs give the boom?
