## Overview

The Vencetmat Guitar String Action Gauge is a high-precision, multi-functional luthier tool crafted from military-grade stainless steel with a 1mm thickness for durability. Featuring laser-etched, permanent graduations with ±0.05mm accuracy and a 4-edge fret rocker design, it enables precise string height, fret leveling, and slot depth measurements. Its anti-glare black plating and ergonomic chamfered edges enhance usability, making it an essential instrument for professional guitar maintenance and setup.

## Description

The string height measurement method is very simple: Bottom of string at 12th fret meets the top of the line. Fret rocker, String height gauge, and slot depth measurement all in one, Stop pay more for fragmented tools. Product Features: -Made of high hardness stainless steel, Handles any rough movements and drops. -With 4 lengths edge, easily span any three adjacent frets. -Every contact edge is very straight and smooth. If abnormal wobble is perceived, that is where the buzzing fret located, rather than the uncertainty that a product with jagged edges gives you. -The markings are etched by a high-precision laser and then manually colored for a permanent presence. -Each side of edge is finely chamfered, refusing any sharpness, refusing any scratches. -The 1mm thickness completely negates the disadvantage of paper-thin and easy-to-bend, This is why it can only be inserted into slots with a width greater than 1mm,such as bridge slot. -Elegant black plating avoids mirror reflections, which you don't want to encounter. The white marks make reading clear and easy.This is necessary for people with poor eyesight. -Accurate graduations is necessary for accurate measurement of string height, and the error of the graduations is always kept within 0.05mm(1/5 of the hair diameter).-Metric,imperial,64th marking all in one, which is very useful for people not skilled in metric/imperial conversion.-Compared to other similar products, we removed one graduation(0.25mm/0.01in) that was useless for all stringed instruments and added two graduations(3.75~4mm/0.15~0.16in). Why? While the low string height brings a comfortable feel, it also loses sound quality. For classical guitars, 3.75~4mm(0.15~0.16in) is still an option.These two graduations will bring more possibilities for classical guitars.

Review: Don't buy this. Go elsewhere and pay a bit more for one that'll do the job properly. - Couldn't find any way of contacting the seller direct, therefore here's an honestly review. This fret rocker needs to be a precision tool to do it's job properly. See photos, quite frankly it's a disgrace! When I tried it on a decent guitar, every fret appeared to be rocking, and not in a musical way. I immediately thought, something isn't right here! After checking the rocker on a known leveling tool, it became apparent this was not suitable for purpose. Do not buy this fret rocker, it's a piece of crap! I should have known better, you get what you pay for!
