This is a finger rest compatible with 4-string JB type basses, such as Fender. Originally, this product was sold as a finger ramp and finger rest, but at the suggestion of a customer, it was made into a finger rest only. It can be installed without drilling holes in the pickguard. ■ Product Introduction ・ Can be attached and detached using the pickguard's fixing screws. ・ Screw-on type, so it won't dirty your instrument. ・ Uses a high-precision 3D printer and incorporates design ingenuity, so we are confident in the surface finish accuracy. ※ Less surface roughness and fuzziness, which are characteristic of inexpensive 3D printers. ・ 3mm thick (assuming the pickguard is 3mm thick). ■ Colors ・ Please choose from the 7 colors shown in the image. ■ Warranty ・ In the unlikely event of a product defect caused by us, we will remake it free of charge after confirmation. If you have any other questions, please feel free to contact us. We also sell other equipment accessories made with a 3D printer. Please take a look. #JazzBass #Bass #Fender #Fender #4String #FingerRest #FingerRamp #Accessory
