WD40 on neck and strings speeds up playing
I've actually seen a guitarist do this on a PRS at a gig. I know him too but 'kept stoom' as the bloke can play really well, but thought, what the hell are you doing to that guitar?
Anyway this thread is gold! Watching and listening to the deluded digging their own hole is fantastic entertainment! Your so lucky to have this prat as a housemate. Set him up with some auditions with quality musicians and go along and watch his world fall apart! :lol: In fact film it and send us the youtube link!
