It's difficult to capture its characteristics in a photo, but it has a dull, smoky silver color, and the texture and light reflection are different from other colors, giving it a heavy color scheme. This is the GOTOH Floyd Rose type tremolo unit, "GE1996T". Made in Japan, GOTOH is renowned for its high-quality, premium parts! GOTOH's unique torque-adjustable arm, stud lock function, and above all, its high precision are unmatched. The sustain block is the standard 40mm specification.

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.
