I just got a hipshot bass x-tender BT1 for my Sterling by Musicman Ray'34, but it doesn't fit at all. Despite being advertised as a direct drop-in replacement for Musicman and G&L basses, the screw holes don't line up at all to those of the original tuner, and the shaft is tapered differently as well (though it fits, so that's merely an aesthetic issue). Additionally, the actual key part is slightly differently shaped and sized than those of the other original tuning keys.
Here's a pic so that you can see how they're differently shaped on the back (leading to the screw holes not lining up).
Obviously I'm going to return it and get a different tuner, as I really don't want to start in with drilling new holes on my baby. Is this some sort of misunderstanding? do the Sterling by Musicman basses use different tuners than the actual Musicman basses? Any suggestions?
On a side note, after looking at all of the pictures of the different sorts of Hipshot bass xtender keys, the shape of the plate on the back of my tuning keys looks somewhat similar to the Fender keys. Should I get a fender x-tender?
