Well since I've sanded the paint off my 55-01, (looks great by the way), and have just recieved a lil b-day money...I had the idea of upgrading electronics on the bass. One crazy idea since I have access to all sorts of woodworking tools....is routing out room for a music man pup. I guess I'm looking for something more aggressive than the stock Barts...would like to change out the neck pup as well. Any suggestions? Is this advisable or not???
