Hey. First time TalkBass user here, with a fairly specific/situational question. I play guitar in a rock/punk/folk two-piece, and have been pretty happy with a three-amp (guitar/guitar/bass) setup for the last couple years, where I split the signal from my guitar into a guitar chain and a bass chain (clean, no octave), and then into their respective amps. Simply put: I have AC30s for tone, and a bass amp for root emphasis. It sounds huge. I've been going through/burning out bass amps a little more often than I would like, and even though I think it's more of an issue of used gear and bad luck than anything underlying, I would love to get some suggestions on what to try next. My latest experiments: Hartke 3500 head into Ampeg 1510 cab pros: 10-band EQ plus more generic "high/low" adjustability, plenty of power, tube preamp cons: Rack-mount head (with no rack to mount it), I either get only the lowest of low tones, or too many mid/highs that interfere with the AC30s. I guess I'm looking for strong low/mids, and this doesn't do it. GK MB115-II combo pros: portability (super light), reverb (albeit digital), actually pretty decent in the low/mid range I'm looking for, fairly cheap new. cons: not enough power (had to be cranked all the time and caused some overheating issues), solid state tone isn't so great, sounded muddy when turned up. My first preference is to keep using the 1510 cab for now with a new head, but ANYTHING you might have to suggest to me would be greatly appreciated. I'm open to some more expensive/exploratory ideas, but may still have to research and budget accordingly. I am also happy to answer any questions about my playing style, pedals, tone preferences, etc.. if it might help stir up some ideas. My end goal is to have a strong rock guitar tone, with chord changes that make the room shake... and I don't think I'm far from that. Thanks a lot.
