I've searched, and this question hasn't been asked/answered in a few years. This is the only one anyone has mentioned. It's the MEC pot that comes in certain Warwick basses. It would be perfect if it didn't have the extra switch in it, making it too long to be practical inside most guitar control cavities. I was wondering if anyone has in the meantime made anything similar? Or if there is a company that can be sourced to do so?
