New! Made in Japan High Quality Genuine Gotoh Tremolo Unit Specifications ◆ Model Name: 510T-SF2 ◆ Finish (Color): C / Chrome ◆ Type: Tremolo Unit ◆ String Pitch: 10.8mm ◆ 6-point support type ◆ Contents: Bridge body, arm, mounting screws x 6, springs x 3, spring holder, holder stop screws x 2, 2 types of wrenches, instruction manual GOTOH, boasting the best technology in Japan! This tremolo unit is the flagship model of GOTOH, bearing the number 510 (Gotoh). GOTOH's own patented features include a reliable stud lock mechanism and an arm with adjustable torque. The FST mechanism, which secures the strings in a hollow space to maintain more consistent tension, is just one example of the top-notch Japanese technology used. ★ The difference between 510T-SF2 and 510T-FE2 is the saddle! SF2 uses a bent-type saddle, producing a natural and warm sound. FE2 has an integrated saddle, resulting in a clear sound with excellent sustain. SF2 is recommended for those seeking a more natural sound or an old vintage sound. Of course, the best tuning accuracy remains! As expected of GOTOH's flagship model. The nut and bridge (tremolo unit) are where the vibrating strings first transmit their vibrations. If you cut corners here, it won't matter how good the body and neck wood are.
