Does anyone know where/how I can get a thumb rest that I can attach to the pickguard that looks like it came from the factory from Ernie Ball? Or perhaps a pickguard that comes with this already "built into" it? My main concern is that it looks good. I could just attach a "ghetto" looking piece but I would rather it look clean and "stock", if you will. I'm having a hard time getting use to using my plucking hand over the pickup, and it feels totally weird without a thumb rest higher up where I usually play on my jazz bass without that thumb rest there. I'm sure you all understand what I'm talking about. My pickguard is black. Anyone?
