Hi. So, I've ditched the pick and finally gotten the hang of playing finger style. It's great. I rest my thumb on the big MM style pickup on my bass. I rest it there all the time, even when I'm playing on the bottom string. Doing this works for me, but is this a bad habit? I've noticed bassists usually rest their thumb on the string above the string they're plucking. Now that I think of it, that would be great for muting, but it doesn't feel right. If I were to pick up a 6 string bass and play it, would I have trouble resting my thumb on the pickup as I do now and reaching the bottom strings? Currently I use a 4 string bass and my thumb position works well. Should I make myself rest my thumb on the string above the one I'm playing even though it slows me down? I could probably get the hang of it if I tried. And while you're answering this question, tell me where you rest your thumb. Thanks.
