HAUUFENN String Height Gauge Stainless Set with Fret Polishing for and Bass Guitars Maintenance Set, Steel, 3-Piece (8.6cm), Plate, Electric,

[Easy to check string height] This string height gauge features both millimeter and inch markings. By placing it vertically near the fret you want to measure and reading the height to the bottom of the string, you can check the string height of your guitar and compare it before and after adjustment. [Multiple scales in one place] Different scales and notches are placed on each side of the main body, allowing you to check string height and fret dimensions from multiple positions. This design makes it easy to work without having to switch between multiple guitar rulers. [Protects the fretboard while working] Two fret polishing plates of different widths are included. By threading the strings through the slits and aligning them with the frets, it becomes less likely for tools to touch the fretboard during fret polishing and grinding work. [3-piece set contents] This set includes one string height ruler measuring approximately 8.6cm x 5.8cm, and one protective plate each measuring approximately 7.8cm x 2cm and 7.8cm x 1.2cm. You can use them according to the fret width and working position. [For daily maintenance] This product can be for maintaining electric guitars, acoustic guitars, basses, and other guitars. It is a guitar maintenance product that assists with checking during string changes, adjusting string height, cleaning around the frets, and practicing repairs. This guitar maintenance tool allows you to check string height and perform fret work all in one go. The ruler is placed between the strings and the fretboard to read the height, and the protective plate is as a fretboard cover when polishing the frets by threading the string through it. It's convenient for checking and adjusting electric, acoustic, and bass guitars, as well as when changing strings.
