This is a finger ramp with a finger rest, compatible with 4-string JB type basses such as Fender. We have incorporated customer feedback to create an improved Ver3 product. ■ Product Introduction ・ Can be attached and detached using the pickguard mounting screws. ・ Screw-on type, so it won't damage your instrument (no drilling required). ・ Pickup height is also adjustable. ・ 4mm thick (pickguard thickness is assumed to be 3mm, 2mm thickness is also available). ■ Colors ・ Please choose from the 11 colors shown in the images. ■ Warranty ・ In the unlikely event of a product defect caused by us, we will remake it free of charge after confirmation. ・ We use a high-precision 3D printer and have put effort into the design, so we are confident in the surface finish accuracy. ※ There is less surface roughness and fuzziness typical of low-cost 3D printers. If you have any other questions, please feel free to contact us. We also sell other equipment accessories made with a 3D printer.
