Hi. I've been gigging extensively as a covering bassist, mostly in one group with a very varried repertoire. I've used one of those coffin sized ampeg 8x10 forever. And I admit it gives a great all-purpose response and generally does all types of bass well. My amp is excellent at handling varriety at the click of a footswitch or worse case the turning of a knob in between songs, being a M9 carbine mesa. But I'm craving more and my cab is pretty beat too. I'm wondering if I can have the best of all bass types. I want the super low feel of say regea or some pop tunes with a 15'' or bigger. But I also want the stop on a dime precision and clarity while slapping some flea, claypool, or playing some more midrange gritty punk of the multiple 10s. Can I have the best of both by using a 1x15 and 4x10s with my M9 carbine? How best to go about this? And since I make money from gigging so much and work full time...I'm not too squimish about cost. What are the best single speaker large cabs and 4x10 cabs? I dream that this will give me an ideal set-up. I try to avoid running thru PAs as much as possible since I'm a control freak. There are only a few venues I've played where size makes this impossible. So with that said, basically I'm looking for the best all around sound for a varriety of bass styles even in the same set. Thanks for reading!
