I just bought a Sadowsky MS5. It is absolutely fabulous, but the tuners(especially the G-string tuner) make annoying buzz. I took them all out of the bass, and tightened the screws. No difference, the buzz is still there. It is annoying, because I like to play unplugged. So, is there anything to do? I didn't tighten the hex-screws, could they make the noise?
