The Gotoh SD90-SL-AGN is a complete set of tuning machines for electric or acoustic guitars featuring a 3+3 configuration and a vintage Kluson-style design. Its aged nickel finish and SL tulip-shaped buttons provide a classic aesthetic, especially suitable for instruments with a traditional-inspired look or guitars with a vintage finish.

With a 1:15 gear ratio, it allows for precise and smooth tuning adjustments. This model uses standard posts and does not incorporate a locking system, maintaining the traditional operation of vintage-style tuning machines. It’s a great choice for build projects or replacing a compatible tuning machine, though it’s recommended to verify installation measurements beforehand.

Our Opinion

An especially suitable option for restoring a classical guitar or completing a project that aims for an authentic vintage aesthetic. The aged treatment prevents the overly shiny look of a new tuning machine and pairs well with guitars that already show wear or relic-style finishes.

Its 1:15 ratio offers a good balance between tuning speed and accuracy. As a traditional non-locking tuner, it maintains the classic appearance and operation of the Kluson style. Before installation, we recommend checking the diameter of the original holes and screw positions to ensure proper fit.
