I'm making plans to drop one of the Gibson EB-size humbuckers into an 80 MIJ parts bass. The body is a rear routed Jazz bass special (which is actually P-shaped), and the neck is MIJ jazz bass. I'm going to fill the j-pup space, rout the neck pup position, refinish the thing, and drop in the Gibson 'bucker. I know the bassist from Grand Funk Railroad had a similar setup in his J Bass. How does that sound for a fun project?
