Just interested in others thoughts about this... I play a Lakland 55-02 with Barts through an Acoustic B200 head and GK cabinet with 2x10 Eminence Delta 10a's. http://eminence.com/proaudio_speaker_detail.asp?web_detail_link=DELTA-10A At rehearsal volumes, my low b string sounds great - pretty tight and punchy on low d's, eb's. Played a gig last night and didn't feel my low notes had near the presence as at rehearsal - played in a small bar-sized venue with full subwoofer reinforcement. I'm not sure exactly how it sounded in the house, but know my low notes just didnt have the punch on stage, even though my amp was turned up louder than at practice. I tried different eq setting and still felt I couldn't isolate the particular frequencies that matter in terms of the b string. Any advice, thoughts? In the market for a new amp and cab - thinking SWR Headlite and a smallish cab - maybe 1x15 or 2x12... What do you think? Thanks in advance.
