Specially designed as a direct replacement for standard Rickenbacker® 4001/4003 bass guitars or as an upgrade for Chickenbacker basses the SlimJim® surround is made of stainless steel and acrylic and will allow you to fit your pickup of choice in the treble position on your bass.
The kit is supplied with the four small screws needed to fit directly onto your Rickenbacker without the need to drill any holes. Fitment to non-Rickenbacker models may require holes to be drilled or the pickup cavity to be enlarged. It also includes two M5 machine screws with springs and a black nylon pickup caddy which has holes pre-drilled to allow you mount the pickup of your choice.
The size and shape of the stainless surround is identical to that of a standard Rickenbacker surround so you can easily switch without having to alter your bass or drill additional holes.
