This is an old guitar. Since modern parts offer better performance, how about using it as a modification base? I have cleaned accessible areas, but I haven't disassembled it for cleaning. The screws show signs of rust, so I recommend using a wrench like a Vani-dora when turning them. I don't know how to adjust the pickup height. * The pickups touch the strings when the string height is lowered to about 2mm for the 6th string and 1.6mm for the 1st string. Currently strung with Ernie Ball 10-46 strings. One knob is missing. Both the top and back have a deep arch. The binding is in good condition, and there are no cracks in the body, but there is overall clouding. The pots' functionality is unknown. Contact is poor, so the wiring needs to be reviewed. * Due to its hollow body construction, familiarity is required when working on the assembly. 【SPEC】 ◆ Year: 1960s ◆ Model: ESP-230 ◆ Neck ・ Truss Rod * Turns somewhat left and right, but is stiff. ・ Fret Remaining: 70-80% Please refer to the photos as the original height is unknown. ◆ Tuners: Functional and adjustable * Some tuners have stiff torque. ◆ Pickups: Sound output confirmed ◆ Weight: 2.7kg ◆ Accessories ・ Soft case Type...
