Hello fellow bassists, When plugged in, my Ovation B778 acoustic-electric bass produces a wonderful sound from all stings except the E, which sounds hollow (as if the pickup is not working properly). The type of pickup is a "Tru-Balance" and is part of the bridge assembly. After further investigation (taking apart my bridge) I discovered that the end of the pickup wire (which is located under my E string) produces very little sound when tapped (as compared to the rest of the line). Other than visiting my local luthier, what other options might I have to remedy this issue? Is my pickup shot? Does it need replacement? Might there be an internal issue that can be easily fixed? Thank you for sharing your thinking & help.
