Gotoh 510T-FS1 Tremolo

Note: This model has limited availability and may only be stocked by select retailers. See below for fitment and alternative options.

The Gotoh 510T-FS1 is a high-precision 2-point tremolo system designed for Strat-style guitars with narrow 10.5mm string spacing—a common spec on many Japanese Fenders, Squier Classic Vibe models, and other import guitars. Part of Gotoh’s respected 510 series, the FS1 offers premium materials and manufacturing with a focus on tuning stability, smooth action, and tonal integrity.

This bridge features solid steel saddles, a steel tremolo block, and Gotoh’s patented FST (Fulcrum Stabilizing Technology), which helps the bridge return accurately to pitch after tremolo use. The push-in trem arm provides smooth feel and adjustable tension. It’s a non-locking bridge, so ideal for players looking for modern performance without a locking nut.

️ Installation Notes

The 510T-FS1 is a direct-fit replacement for guitars with a 2-point tremolo post system and 10.5mm string spacing. This narrower spacing is common on many non-US Strat-style guitars, especially Japanese-market Fenders, Squier CV series, and some Ibanez S and RG models.

It’s not compatible with vintage 6-screw bridges or guitars using 10.8mm or 11.3mm spacing without modification. The system includes mounting studs, claw, trem arm, and springs.

Because of its narrow spacing and precise construction, this bridge helps eliminate issues like string misalignment at the fretboard edges, which can occur when using wider-spaced bridges on narrow-necked guitars.

️ Availability Note

The FS1 is less commonly stocked than other Gotoh 510 variants and may require special ordering from niche retailers. If your guitar can accommodate 10.8mm string spacing, you may consider the Gotoh 510T-FE1 as a more readily available alternative with similar performance.
