Schaller Bass Machines, Set of 4-In-Line

"Elephant ear" bass tuners with smooth 20:1 gear ratio and slotted string posts. 11/16"-diameter pegholes required.

These machines can be disassembled to reverse the worm gear shafts for left-hand pegheads when required. Screws and press-fit bushings included.


Pilot holes required: Installing delicate screws such as these into hard maple requires great care and accuracy. We highly recommend using a 5/64" bit for the pilot hole before installing these screws. Lubricate the screw threads with cutting lubricant (also wax or a bar of soap) to reduce friction and help them thread properly.
