Hi John( jmas 05),
Thanks for listening.
You are partially write😎.. I actually used three mics: a regular AB couple in front of the guitar and an additionnal one placed towards the lower part of the body to bring some " highs" .
A really efficient trick in thoose cases was given to me by a friend which is to give a clap at the end ( he said at the start) so it comes really easy to align the audio of the different mics. Actually I think one clap at the start and one at the end should be the best process so you can check if everyone in the court remains synchronised.
Cheers.
Olivier
