he plays blues. he definitely had an electric, and i want to say it was a fender. i think he would be rusty for sure; i wouldn't be surprised if he hasn't played for a year.
he definitely isn't the type of person who would want lessons, and with his busy scheduled he'd never go anyway. i was thinking about trying to set him up with some sort of midi interfacing hardware/software where could plug in his guitar and play some sort of app/game that helps him shake off the rust.
a confounding factor is that he has also has De Quervain's tenosynovitis, which is a wrist/thumb issue, and this might have contributed the decrease in his time spent playing guitar. but i think he'd still be grateful for guitar stuff even if he is physically limited in what he can do
by the way, i really appreciate the help everyone. he definitely deserves something nice this year, so it means a lot to me to get these great suggestions
