Speaking of Jack and Jorma... and set-ups:
You may know that Jorma and his wife, Vanessa, have a guitar camp in Ohio (Fur Peace Ranch). It's a wonderful place for players to commune and learn and teach. As a bass player, I have taken a bunch of sessions with Jack as the teacher. Part of one session involved setting up a bass, Casady-style. He sets up his Epiphone Jack Casady models with the neck absolutely FLAT. He also plays with some high action, at least compared to what I am used to. His tone is from God!
