(If this is the wrong forum... feel free to move.) I have an Ampeg SVT CL w/ a 410 cab. It has a great sound. My only complaint, and I really hope it's not the amp at all, is the booming, loose low end. How can I tighten up the low notes? My prescence in the band is definitely felt, and heard, but any note played on the E string just rumbles out uncontrollably. Maybe it's the acoustics of my practice room? The highs are just as crisp + punchy + clear. The lows seem to travel in all directions. How can I get a better, tighter (dare I say "thud") sound out of it. Maybe some type of pedal is my answer? Any insight/advice would be great. Oh yeah, primary bass is a MIA Fender jazz with rounds. Thanks.
