Jaras 4-in-1

Precision made from aluminium. Takes the guess work out of grand regulation. Will last a lifetime and pay for itself many times over. Completely dissassembles for compact storage.

String Height Gage Attachment

Insert into either of the two stands. By placing underneath the string an accurate reading can be obtained from the ruler gauge.

Backcheck Gage Attachment

Insert into stand like string height gauge attachment and set at the same reading. The bottom of the bent rod will be 5/8" from the strings. When the hammer is the same height as the bottom of the rod, the backcheck will be properly set.

Damper Lever Height Gage

Insert into base of the stand and set the top of the extended part of the gauge under the damper lever. This measurement should be made when the hammers are half-way elevated or keys half-way depressed.

Let-off Rack
The let-off rod is then replaced into the stand and set for 1/16" lower than the string height reading. Now you are ready for let-off regulating.
