Performing artists stay in tune with Waverly:
"I love Waverly tuners. The keys move with ease and hold b, two important qualities we must have to perform night after night. I have Waverly tuners on all my mandolins. I wouldn't want to use anything else. They are the best!" — Rhonda Vincent

Installation Tips
Peghole spacing:
Plate-mounted tuners can't work efficiently if the pegholes are improperly drilled. Our Mandolin Peghead Drill Jig (sold separately) ensures precise 29/32" spacing for accurate alignment.
Bushings:
Get the right fit! We highly recommend the use of a .328"-diameter bushing reamer to cut a clean, accurate counterbore for a professional job.
Mounting screws:
Pilot holes required. Installing delicate screws into hard wood 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.
