This module creates a freted position anywhere on the frame, each module has four separate frets for each string which can be placed in the sloted grooves spaced out at 2mm intervals. The placement of each fret needs to be pressed into the slot and requires a tuner to get it to the right position for the intended pitch.

If using more than one module the overall height of each module is calibrated using the two screws on the front, for non buzzing efficiency each module needs to be slightly lower then the previous one. Once you set their order and heights the first time keep the same order for next the next uses as the plastic will slightly deform and may not recover from it’s first setup. We provide labeling circles for this purpose.

The photos of the frets in use show the ADDAC128 Frets instead of the 128M.
