Re: Edge pro 2 vs Edge 3
First of all, the Original Edge doesn't "own" the Edge Pro. With the higher quality trems like the Edge, Lo Pro Edge, and Edge Pro, it boils down to personal preference. I've recently had the chance to play all of the different Ibanez trems set up properly and I will definitely say that the Edge Pro is every bit as versatile as the Edge and the Lo Pro Edge.
Of course, the Edge Pro II and Edge III are for regular series Ibanez guitars so they aren't quite as good. Having recently owned both a guitar with the Edge Pro II and with the Edge III, I would say that the two trems are about the same quality. The Edge Pro II is lower profile than the Edge III, however.
