LIMITED EDITION Prototype Sloane Classical Tuners with Aluminum Rollers
Only 12 unique sets available.
When they're gone—they're gone.
These prototype tuners were developed by our Waverly team as part of a short-run experiment: replacing traditional white or black rollers with sleek, lightweight machined aluminum rollers. The result? A beautifully modern look and feel that stands apart from any tuner we've ever produced.
Each of these 12 sets is unique—only one of eac combination of button materials and plate designs—all united by the exclusive aluminum roller upgrade. We're not planning to put these into production, so this is a rare opportunity to outfit your classical guitar with something a true one-of-a-kind upgrade.

Installation Tips
Drill pilot holes for for mounting screws:
Installing delicate screws into hard wood requires great care and accuracy. We highly recommend the #1711 Depth-stop Drill Bit (No.50 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.
