Working on tone and technique. Here's a question: Is it better to relax the left hand thumb and play with the fleshy part agaist the neck or is it better to employ the thumbtip like a claw? Iv'e been trying the later and it seems really hard to get a good tone and it seems unnatural and makes my hand tired. Will this change over time? I'd really like to get a tone like Brian Torff. Any suggestions would be great.
