I'm not happy with the sound I'm getting from my current rig....I'd like to reduce the weight of my rig and improve the sound....cost is not a major issue....I'll pay up to optimize quality of sound and minimal weight tradeoff. I play my '72 P Bass most of the time but switch back and forth to some extent with a Spector Fretless NS-2J. Current rig is a Workingman's 4004 head driving Workingman's 1X15 and Peavey 410 TVX. Components were acquired piecemeal over time. The sound is muddy and seems to deteriorate during a performance....presumably as the 4004 heats up. I'm looking for a thumpy, ballsy low end but clear notes in all ranges. Oddly enough, I get a sound I'm quite happy with when using my little CRATE BX-25 with my SABDDI for practices. It's just not powerful enough or loud enough for a big room. So, any advice/thoughts would be appreciated.
