Bass Bridge Adjusters

Our adjusters are based on a 1/4"-20 TPI format for all three models. The size was chosen to be interchangeable with the Fishman Full Circle pickup.

The two wheel thicknesses have the added benefit of allowing luthiers to make a quick bridge height adjustment without cutting the bridge. The wheel diameter is on the large side for easier turning. Properly installed, you can easily turn them up with two fingers under full tension.

The aluminum models are a black anodized one-piece design made in the USA just a few blocks from us in Fairport. The quality of the threads and the smoothness of the wheels are a pleasure to work with at the bench.

The wheels for the Otto Ebony are made in Suzhou by Sam Shen's craftspeople, with the shafts made and assembled in the US.  They offer a sophisticated look that is softer on your fingers.

Installation is available for dealers in our bridges or yours.
