I'm having trouble keeping consistant punch w/ my current bass rig. I'm using a peavey 500w 4/10 cab w/ an ampeg svp pro preamp and a crappy 400w power amp I got from my guitarist. When I'm standing right next to my rig it sounds awsome. It's got the tone I want and great punch. When I'm 10 feet away it sounds like crap. The tone is still decent but there is no punch. Is it a frequency thing, or maybe the amp I'm using? Any help would be great. BTW it's a 5 piece metal band and I'm playing alot of ryan martini style bass lines. Sorry, this was meant for bass, not double bass.
