FWIW - Neo Classical Shredder / Instructor, Rusty Cooley now plays a multi scale guitar. He is the most accomplished guitarist I’ve ever seen. (I had a lesson with him once) The guy has devoted his life to playing guitar and I’ve never seen anybody play that well before in my entire life!

I just thought I’d throw that info out since we’re on the subject of extreme guitars and extreme players.
