Thank you for viewing! The product is a "Finger Ramp for JB, Front, Bridge Side." It's designed to be small and fit on the pickguard so as not to detract from the Jazz Bass aesthetic. The dimensions are: Width: 91mm Length: 28.5mm on the 4th string side, 47.5mm on the 1st string side Thickness: 7.2mm near the center, 5.2mm on the 1st string side (The 3rd string area is the highest) There is a recess to avoid interference with the pickguard screws, but it's been matched to my own. If it interferes with yours, please remove the screws. It is made with a 3D printer, and the material is PLA. Unlike typical plastics, the surface is not smooth and has small bumps. Thank you for your understanding. Double-sided tape is included, so please use it to attach the ramp. Thank you for your consideration.
