The trem arm is a bit long for my liking, has anyone modified this, is it possible to remove the tip and saw an inch off and push the tip back on the shortened arm?
I’m sure you could. I shortened a Strat trem years ago. The plastic tip was screwed on and it worked fine just pressed on the shortened arm. You can always order a new trem arm from Music Man.
I've thought about doing this myself, only thing that stands in the way is that the metal/plastic tip screws onto the end of the trem arm... you'd have to super glue it on to the arm or something after resizing it (or re-thread the arm), but as dude above mentioned above you can always order a replacement from EBMM.
