So I have a geddy lee jazz bass, and love it, but I've been craving a Pbass lately so I've decided to build one to my liking. I already bought a S&D 1/4 pounder pickup for it. My question at the moment is more about the neck. I was thinking of getting the same neck thats on the geddy lee onto the precision body, but I wasnt sure if the neck cavity is the same size on the two, anybody know? Also I was weighing the option of getting a finished neck from warmoth that would be close to the same specs. Should I bother going through warmoth or just find someone thats getting rid of their geddy lee neck? I've never played warmoth neck, but heard great things. I'm sure I'll return with more problems and questions as the project rolls on, at the moment it's still in the planning stages.
