Re: recording a classical guitar performance

Why in heaven's name would you need to hide the mic? These are Concert Venues. Do you think they don't know that recording requires microphones?

He's AUDITIONING for gigs. They want to HEAR as clearly as possible how he plays. Period. They'd also, I'm sure, like to watch his hands and playing technique. Nothing else really matters.

I'd take the TLM-103 and mount it on a mic stand with boom arm and place it about 10 inches out from his forearm and facing directly at the sound hole.

Listen and adjust. Particularly the lower registers. You want rich, warm bass notes - something that too much distance from guitar to mic will fight.

The TLM 103 should have no problem with that or with reproducing a guitar with both clarity and a nice "live" sound with lovely spacial sense of the room.

Maybe a little more angle to to the players body so that the people judging the effort can easily see both his right and left hand movements.

But that's it. You should get an EXCELLENT recording of the guitar. And in this situation, that's what really matters.
