Im finding myself anchoring my thumb on the B string while I play notes on the G and C string of my bass. Is this proper technique or should my thumb be floating or anchor on a higher string when I go to the higher strings? I would anchor it on the E string on my old Fender 5 when Id go higher, but for some reason with this bass Im not doing that. I know Im picking up and have probably picked up a bad habit or two while learning this new bass and I'm trying to correct them before they become really bad. Thanks in advance!
