I'm not sure where to post this so forgive me if it's in the wrong section. I'm considering the purchase of a short-scale bass and would like to know if the pickups on the Slammer Special (30.5" scale) are of a 'standard' size. Can I replace them with Bartolini, Seymour Duncan, etc., without modifying the body? Also, does anyone make good replacement pickups for the Fender Mustang Bass? Thank you in advance.
