I am selling my Music Man Bongo 4HH today on CL because I am looking to upgrade to a 5 string. I know someone selling one, but it is the Bongo 5H (single pickup). Does anyone know if it is possible to add another pickup to these basses without compromising the integrity of the guitar? I really want to pick up this Bongo 5H, but feel that I would not want any regrets later being able to only work with the single pickup. Any advise would be greatly appreciated. Thanks, Nate.
