I recently bought a Music Man Sterling Ray 34 which I love! The tone is out of this world and it has a growl that just won't quit! However, I've been noticing much weaker signal/output from the D and G strings. I play about midway between the neck and the p/up. In fact, if anything, my fingers are a notch closer to the pup when I play the D and G. Now, I've had this experience with my P-bass, but it just seems more pronounced with the Sterling. The string are heavy gauge and quite new, as well, as a new battery. Any ideas, explanations, remedies?
