Finger Ramp for JB (Jazz Bass) - Front, Bridge Side I'm selling this because I bought another finger ramp. Here's a repost of the creator's comments: Width of the finger ramp section: 91mm Length: 28.5mm on the 4th string side, 47.5mm on the 1st string side Asymmetrical, with the 3rd string area being the highest There's a recess to avoid interference with the screws holding the pickguard, but it's been adjusted to fit my own. If it interferes with yours, please remove the screws. Made with a 3D printer, the material is PLA. Unlike typical plastics, the surface isn't smooth and has small bumps.
