To me, it's a huge problem that I fortunately no longer have to worry about.
Bass amps and cabs were for me, always on one side or another of this fence:
Line up all the usual suspects (Fender, Peavey, Sunn, Acoustic, etc., augmented by later, supposedly 'smarter' rigs like SWR, Eden, and Trace, MarkBass, and all those who followed in the Trace / SWR wake), and these were all 'bass amps', built for the guys who sweat out the five and six night a week sitdowns with Fenders or Musicmans or any of their clones.
Then the other side of the fence: Rigs built primarily from Sound reinforcement / studio gear. Channel strips, dedicated bass preamps, commercial power amps, Demeters, Millenias, Universal Audio, dBx, rack gear of any and all persuasions, and God knows what kinds of cabinets, from straight touring cabinets to more esoteric bass guitar cabs like Acme, etc. For guys playing Alembics and Ritters and all sorts of 'furniture' basses.
Spin the wheel and it's a crapshoot what will work well in any given room.
And then, does my fabulous tone I built solo VANISH when mixed into the dizzying randomness of a band situation: Did I do all this to get buried by a doofus with a Marshall half-stack, will my standing wave (just had to have that five-string, didntcha?) knock glasses off the back bar, this gig has NO PA and I'm TOO LOUD anyway, this gig has a fabulous PA and I didn't need to bring all this . . . . . my brain melted just re-hashing all this.
Then I go to see a band, and the guy has a crap PBass and a rusty Peavey stack and sounds great. Sigh . . . . .
I COMPLETELY understand why Jimmy travels with a direct box and wedges.
I spent my playing days completely understanding that the bass+amp+cabinet=my instrument. I also never mastered my sound, spent a lot of time fighting rooms where I could not hear myself while roasting everyone else, and always felt I was swimming uphill because of it. I once read an interview with Joe Osborne where he said he way preferred the studio, as he couldn't ever hear properly on the gig. I know . . . .
Where's the Tylenol ?
