It can also be used to measure other parameters, such as pickup height. Compact and portable, the gauge is easy to carry in a guitar case or toolbox.

Its metal construction and gray finish make it more resistant to the effects of time. This model is compatible with all stringed instruments and helps optimize playing comfort, prevent fretting, and improve tone.
