Fender String Action Gauge

Accurate Setup Measurements for Consistent Playability

The Fender String Action Gauge is designed to remove guesswork from guitar setup by providing clear, repeatable measurements for string and pickup height. Precision-etched into 20-gauge stainless steel, the gauge offers durable accuracy that holds up to regular bench use and on-the-road adjustments. Dual-scale markings allow measurements in both inches and millimetres, making it easier to work to preferred units without conversion.

An integrated reference chart displays factory-recommended string action values for electric guitars, acoustic guitars, and bass guitars, helping users make informed adjustments rather than relying on feel alone. The etched markings improve visibility and reduce wear over time, supporting consistent results across multiple instruments. With a compact 3.5" × 2" footprint, the gauge fits easily into a guitar case, gig bag, or tool pouch, and the included protective case helps prevent damage when travelling.

This tool supports precise setup work that can improve intonation consistency, reduce unwanted fret buzz, and tailor feel to the player’s preferences.

At Riffs & Licks Music, we think this string action gauge is best for players and technicians who want reliable, repeatable setup measurements, because consistent action settings directly affect comfort, tone, and overall playability.
