Rufus Reid where he talks about having as much control of your sound from the stage so the soundman has little to mess up.
That's right but the soundperson is fully capable of screwing up without your control no matter what you do.
Case in point: Last Saturday afternoon, outdoor festival, 2 set show. Louder band, I don't bother with a mic. Sent a DI from the Focus. Very low stage volume for me, I always play the PA on these gigs and get just my pitch from the stage rig. He gets part way through the set and my bass starts feeding back like mad. I also notice the harder I play the quieter I get. It's pumping through a compressor.
He squawks through the monitor talkback between tunes something unintelligible, I say over the PA out loud perhaps he should turn off the compressor on the bass and let me control my own dynamics. He throws up his hands, turns off the compressor. No more feedback the rest of the show. It felt much better from stage. Low end was pumping and it was quiet between tunes. I'm sure it didn't sound like an acoustic DB out front but I'm also sure it worked as a "good" sound. Sometimes you take what you can get.
If he'd have had a mic send it would have been even worse. He couldn't make the DI work right, the mic was clearly past his skill level. If we didn't play quite so loud I'd send a mic signal mixed in with the line before he ever got the signal but sending a mic in addition to the line would have been a disaster. He clearly had no idea what to do with me and was treating my signal like a Rock electric bass.
In this case I'm going to sound like whatever he thinks I should no matter what I send and I'll have little say in the matter.
Point is to try to send as "good" a signal as I can out front and hope for the best.
Second gig, small room PA for acoustic guitar and voice only. No sounddufus. I get to use my mic and line through my stage rig to fill the room. Sounds like a beautiful string bass again. Much more satisfying.
