Thanks very much, Gruuve;
The mic is an SM86; it's their condenser that is road-sturdy. I like it a whole lot. It went into my Carvin powered mixer. Guitar went into a Digitech RP-355 with the right and left headphone output going into one of the stereo channels of same mixer. I mixed it so it sounded good on stage-- guitar and vocal balanced properly, reverb, tamed the 12 string zzzing. Then took the "left-right tape output" of the mixer to my Tascam DR-1 recorder set at 16 bit wave. (At home on my computer I added a little more reverb.) The trick is to set the record level of the Tascam unit at the right level, but without much of a sound check to do it. I record most of my performances that way, and have gradually found the appropriate level. So I just tune up, hit the red button twice, and go. Attendance wasn't so hot at the gig, and it's a big place, and the people weren't near the stage. So with the cardioid mic, the glass-tinkling and chatter noise was minimal. Ha! Sometimes the sound of one hand clapping works to your advantage, but I'd have rather filled the place (Oh sure.....in my freakin' dreams.....) And the lower octave on the 12 string are flatwound strings. That helped a lot to fill out the bottom.
For the house, I gave the sound lady the XLR left and right out of the Digitech pedal and asked her to pan it hard right and hard left. Out of the Carvin mixer I fed her a dry "monitor out" of just the vocals. For the house, she added reverb/whatever as needed. She was pretty happy because I didn't need to get a monitor mix from her; she only had to mix the house. I like that way better also because the usual thumb up vs thumb down thing doesn't really work like we wish it did.
That set was long--I've got a 79 minute disc out of it, and it'll be my new Gig-Demo disc. I was able to keep my attention level right up--almost no brain farts. And the brain fart on the beginning of "Deacon Blues" I was able to edit out;)
