Hello Nelson and welcome to the Cow Audio Forum.
I'm with Bill, you see mics all the time in live classical guitar performances.
The TLM 103 is a dandy mic. I have two of 'em. You might feel the guy out about sound. Some classical guys really hate mics with an elevated HF response because it makes their 1st and 2nd strings sound plasticky. The TLM 103 can sound overly bright when plugged into the wrong preamp. That would accentuate the plasticky sound.
OTOH, it worked quite well for me
here .

Ty Ford
