I have a BC Rich Mockingbird Masterpiece 6 string electric guitar. I've had it just over 2 years and while I really think it's a well-built and beautiful instrument, it doesn't hold it's tuning very long at all. My dad and I were attempting to take one of the tuners off to see if we could find a tightening screw for the gear mechanism and the round threaded post bushing broke off at the thread. We obviously discovered the tuner was a sealed unit with no tightening adjustment. I've looked on the internet for a new set of GOOD tuners and saw the Steinberger gearless tuners on the Stew-mac page. Has anyone used these tuners and are they difficult to adjust? What about re-stringing? Due to the 40:1 ratio, does it take all day to re-string or is there a gizmo I could use to wind them quickly? Any help or replies appreciated.
