The thickness of the lamp will be adjusted simply according to the string height of your instrument. The basic shape will be selected or automatically chosen from several existing types, such as asymmetrical arch, flat top, and symmetrical shapes. If the instrument's setup is unstable in terms of string height, we may suggest adjustments. We also offer sets with the neck (with a discount). Sets with block types are also available (^^) Screw recesses are also provided, and it can be easily attached with the included double-sided tape. We also offer various other shapes, set discounts, and custom-made designs with irregular shapes that completely follow the string height of each string. We offer designs tailored to your playing style, so please feel free to contact us (^^)
