And while I'm at it ... I got a book+CD Rock Guitar Improvisation by Rikki Rooksby (from a FastFoward series), which I didn't appreciate until I got my tascam thing. the cd has full-track recordings of lessons, then same thing sans the lead guitar. I play along, I have tabs right in front of me, and most important -- I can slow down the cd staying in the same key! And the way you can loop exercise -- this is great!
(By the way, I am not Rikki Rooksby promoting himself!)
Merry Xmas and happy strumming to everybody!
