after managing to lose the trem arm of my guitar at a gig, i need to buy a new one. however, having looked at several spare parts sites on the net, i cant work out which version of the ibanez edge is installed on my guitar. its an ibanez rgt42dx. if anybody has a definite answer, or could tell me how to work it out, i'd be very grateful!

thanks in advance!
If you go to the Ibanez site and go to your model of guitar, look at the specs of it and it should have it on there.
Guitar: Cort G290
Amp: Laney LX65R
Pedal: Korg AX3G Multi-Effect
spec site seems to suggest either edge pro 2 or edge 3... fairly certain it was made in 2007.
