Ebow Sliding Mechanism
This module creates a harness and a sliding mechanism for a standard ebow. It allows the user to slide the ebow back and fourth below the strings. The ebow used features the “PianoBow” modification (https://ebow.com/diy-mods) where we sand off the Ebow’s feet so that it can get closer and avoid touching the strings when sliding it back and fourth.
The height of the ebow can be raised or lowered using the four thumb screws.
Provided with the Ebow which can be removed and used elsewhere however without its feet, it won’t be as easy to use on guitar as a non-modified Ebow.
Part of the ADDAC 120 Series.

These merchants probably sell this module. Huh?
