This is the 4003 Treble Bezel Cove. It has an integrated thumb cove. It's designed to fit into the stock 4003 treble pickup chrome surround to cover up the pickup cavity opening when the factory pickup cover has been removed.

It requires no modifications to the bass or additional parts. It uses the existing pickup screws and springs and retains the factory pickup height function.

This is an aftermarket part made in the U.S.A. by Tube Ampology.

These are now injection molded out of Grivory GV5H, a 50% glass filled nylon. For increased stiffness and durability. Cosmetically the surface finish has a light texture. Same great 3D cad geometry for a perfect fit.                   

All 4003 Series Treble Bezels are 100% inspected, numbered and dated.

Just the black bezel ships.
