I would like in the future to put some custom pickups into my bass but the current cutouts are a little long. They are for pickups that are 4.25", and the pickups I'm looking at are only 4.0". Now I would guess that the only real option I have to fill in that space is to get some bigger pickup enclosures eh? Are there any companies out there that would be willing to fit a bigger casing over them? For the record, I have a four string bass, but the pickup cutouts house pickups akin to a "6 string musicman" (quote from the company). And of course, I want to install pickups the size of a four string musicman (4.0") Keep in mind I won't have the bass for a couple months so I might not even want to change pickups, but I'm thinking to the future in case I actually do want to.
