Really easy to install. If your bass is equipped with Schaller M4 tuners, the xtender will perfectly match with the existing holes.
Using: Really accurate, any of both tunings (E and D) are moving during my last session.
It seems to have the same nice reliabilty than the original Schaller
To tune your instrument, take care to the notice. The first time could take a few minutes but after some practice it won't be longer than with a standard tuner.
