Tuning Unit

 Keyless Tuning Unit:

  • Aluminum string blocks on stainless steel spindles.
  • Each strings is attached by two studs in the slide, or with a newly developed string-clamping system.
  • Each spindle is equipped with bearings.
  • The rollers are supported radially and laterally by bearings and slide film.
  • Important: Never apply oil or similar lubricant to the rollers and their axle!
  • Different groove depths (gauged rollers) on every neck to prevent string buzzes.
  • The complete keyless unit is demountable. All parts are replaceable, but with this maintenance-free design it will be hardly necessary. You can expect the unit to last a lifetime!
