Hi. I'm not very knowledgeable about basses, but I have a nice 2003 Fender American Deluxe Jazz bass and one of the tuning machines is broken. I found replacement tuners, but they say they are for the 2004+ models, and that the 1999-2003 tuning machines are no longer available. These sellers indicate that these 2004+ model tuners will require some modification to fit the posts onto the headstock of my 2003. I'd prefer to make no modifications, so any suggestions as to some really good tuners that would fit in without mods? I hear Hipshot and Schaller, but I wouldn't know which models to order. Thank you.
