I have a Yamaha BB5000 fretless, the electronics of which I plan to completely overhaul. Right now I'm thinking something along the lines of a pair of Bartolini M55 or EMG45 soapbars. In order to do this, I will have to do a lot of routing, and the existing P-style neck pickup rout will need to be covered up. So, I'm gonna have a custom pickguard made. My question is this: how do I go about making the tracing? I want the pickguard to wrap around the end of the fingerboard and expose the truss rod adjuster, and have a hole cut out for an EMG45-sized soapbar. How should I go about transferring the shape of the end of the fingerboard onto the tracing I'd send to WD to get the pickguard made?
