Thank you for viewing. This is a GOTOH tremolo unit for a Stratocaster. The block is made of iron, which is said to have a positive effect on sustain. It has 11.3mm pitch saddles, made of steel (sheet metal). It's a vintage style that floats on the body with six points. It was used for a short period, so there are saddle marks and scratches. There is no dirt or rust on the main body, but the box is in poor condition. - Model: GE101TS - Type: Tremolo unit - Accessories: Springs, screws, arm - Material: Metal - Configuration: Bridge, arm, springs, and screws are included. Thank you.
