huendeskes Used for a few hours, American-designed Kahler bearing tremolo - used by Kerry King of Slayer, for example.
The arm is very easy to operate (smooth) compared to other constructions (Ibanez ZR, Floyds), and the bridge can be locked with an Allen screw. Relatively easy to install (4-screw mounting from above). The original Steinberger will be put back into the guitar to preserve its originality. It is currently in the guitar, so it can be tested! I can also ship it.
