I just got heavy gauge strings for my bass recently and I've been working out the strings a bit so I could play Drop B CDLC. As soon as I get to the tuner, that's when I have a problem. As soon as the tuner on the B string hits +20, then it goes all the way back to +999 like it wouldn't register any more than that. Can someone tell me what I need to do to fix this? Thanks.
