Single bridge for Monolina & Monolini

This single bridge is intended to be placed under the strings of the Monolina or the Monolini and to tune the melody strings, like on a koto. The single bridge can be moved freely and thus gives the experienced player the possibility to set any desired tuning.
The Monolina has 5 of these bridges included, but more can be added. Monolini comes without any of these bridges.
