Joe Pass, the greatest jazz player in the universe....and even beyond that, hated to practice, He believed that if players practiced enough during their youth that practice shouldn't be necessary. Note: Don't confuse this with learning new material. His father made him practice eight hours a day. Joe tried the patience of many band mates, managers, and promoters, by not spending hours practicing before a concert. It was customary during his reign for jazz players to stay at the homes of friends and concert organizers. Joe would love to spend Saturday mornings with the children of his 'home away from home' watching cartoons and children's shows. It's said that Joe laughed as loud or louder than the kids. He didn't have much of an opportunity to be a kid when he grew up so he spent as much off stage time making up for it.
Joe once went to Brazil for a much needed vacation for 30 days. During the 30 days he didn't touch his guitar. His first meeting back with his guitar was at a Saturday night concert. His warm up was the sound check.
I found the following phrase about using large triangle picks in an old guitar forum and thought it was worth sharing. "I tried using those big triangular things, but I had to fight off the urge to dip it in guacamole."
