I had my Ibanez Hummingbird refretted and set up by a professional. it has an amazing low action without any buzz. While inserting the Fishman REB was easy, didn't even have to loosen the strings, the pickup is relatively tall, and the only way to adjust the height a bit is by shaving some of the cork off. On my guitar the high E string touched the top of the pickup when fretted above the 10th fret. I don't think shaving off a bit of the cork would have solved it, it compresses when you tighten the screw anyway, so you don't have much to play with, less then 1 mm. Shame I had to send it back, otherwise looked like a solid product.
