Here's a virgin, never been on an instrument Alembic Tunamatic Bridge for bass guitar.
Looks, sounds and feels great. This would be a wonderful upgrade to an instrument, or a
really great bridge to put on one that's being built. Manufactured in the mid 1970s.
It's 3 & 1/4" from end to end, 1" wide with 13/16" of saddle travel (not including the 1/4"
saddle width), the saddles are 5/8" each end to end and crowned in about a 12" radius.
The mounting holes are 3" apart mounting hole center to center and drilled for a #6 screw (1/8").
