Todd: I've been working through your "Technique Builders" book/DVD for 3 weeks now and I must say it has been an epiphany for me. Thanks to your instruction in this book, I'm successfully un-learning 35 years of bad playing habits and am amazed by how effective your methods are. The only real problem I'm having so far is that whatever string ends up under the "arch" on the outside of my thumb doesn't get muted. Of course, if I push down hard enough it will stop but that kinda defeats the purpose. Any ideas on how to solve this without doing anything drastic? Other than that, so far, so good. Thanks, Larry.
