well its got an edge pro II i think, which is supposidly better than the OFRs. So i will get it set up by a pro anyway, to get the action nice and low. Also two further questions. Firstly about this knife edge will it wear out? Secondly i know on my squires strats trem (vintage), that when i push the whammy bar down, the strings actions increases, so if i could pull it up, like on a floyd rose style one, would it decrease? Meaning that if i had really low actions if i used the trem both ways, it would just dud out?
