If the XLR out isn't good enough for you, I'd get a good quality mic and mic the cab. I want my bass to sound like it does coming out of my amp, and a DI defeats your tone.
I've been wondering about this for a while, and it's my birthday, so I'm going to ask: What sort of bands do you play in, and how much do you play out?That's why you have a soundman.
I'm with you, in that I like what I like. But when it comes to getting gigs, I've always found that it's best to build a reputation as someone who is easy to work with.
Fair or not, guys who figure that it's the sound guy's problem to ride their fader, or insist on re-wiring the stage for their rig, tend to spend a lot of time on the sidelines, at least in the places I've played. That covers clubs, music theatre, open mics, festival stages, and churches.
IME, providing solid, consistent levels, getting on and off stage quickly, and being attentive to the sound guy's concerns are all part and parcel of getting callbacks, even though they aren't a direct reflection on your playing.
WOOT!
