I have really enjoyed reading some of the posts, like in the demographic thread so I thought I would start this one.
How do user's utilize BIAB and RB in a live setting? and also being a guitarist, I suffer from "Gear Acquisition Syndrome" so what is everyone using for live performance? Of course, live can mean just you and friends informally or in a gigging situation.
For me, right now I am just playing RB on my laptop into a mixer so I can add a mic and then into my stereo. Along with that, I pull out an acoustic guitar or an amp and guitar while I attempt to sing or my wife, who has a great voice, sings along. Blues, rock, crossover country, jazz, pop. Fun stuff, nothing too aggressive. We both have played professionally (in much earlier years) so now it is just to relax and enjoy life.
At some point, I will probably buy some powered PA speakers and a mixer with effects so we can do informal karaoke at parties with our friends. I am not sure a laptop will be reliable enough for that application but it would be nice to continue using RB in that setting too.
I have a bunch of gear, drums, electronic drums, half a dozen amps, guitars but my main gear is a Carr Mercury amp (love), two custom electrics that I built myself, a bass that I built, and a Taylor acoustic.
Would love to hear what others are doing!
