"When I was first learning guitar I completely submersed myself in it and would play 8-10 hours on average... a day. Sometimes more. Now a days on average I don't play more than 30 minutes to an hour or so on some days... It's hard to think of things to practice when I know every scale and every chord... it's hard to get myself to practice when I can listen to a song on the radio and pick out every chord in the song and visualive the fingering almost instantaneously... As for getting ready for a tour... I'll play 2-3 hours a day... going over the set lists repeatedly... but no, I don't practice that much anymore."
if that answers the question about Satch.... haha. I got it as close to the original quotes as I could from my memory.
