Thank you for viewing. The product is a "Finger Ramp for JB, Compatible with Pickguard." This is a finger ramp compatible with traditional JB basses. The dimensions are: Width: 91mm on the F.PU side, 94mm on the R.PU side Distance between F.PU and R.PU: 73mm Pickguard step: 2.5mm Thickness: 9.5mm near the center, 7.5mm on the 1st string side (The 3rd string area is the highest) It has a recess to avoid interference with the screws holding the pickguard, but it has been matched with my own, so if it interferes, please remove the screws. It is made with a 3D printer, and the material is PLA. Unlike general plastics, the surface is not smooth and has small bumps. Thank you for your understanding. Double-sided tape is included, so please attach it. Thank you for your consideration.
