You know what, I think I may stick with the sterling bridge, now that Ive played the crap out of this guitar and love it, its a really good trem! Its PISSAH! Wicked good! The only thing I would recommend to any sterling ax40d owner is to refinish the neck in the ebmm fashion, I did a thread on this with pics, mine feels incredible and gets better with time, start sanding the neck and fret board with 600 grit then 800 grit and you can do the true oil and wax finish, i used different products because i did a lot of testing, i went with watco's danish oil ( natural) first applied with a rag very vigorously, friction is the key, a few coats, then the next day I used a product called howard's feed and wax, its a paste of carnuba wax and bees wax , with orange oil, same process with the rag, after a few days your neck will be insane!!!!!! Smooth as a baby's ass, but with still the feel of the raw grain, do some experimenting on scrap wood. Ive done this neck finish on three of my guitars and several friends guitars and its great!
