Saw your post on the nice Koa Ibby you got- tres sweet! I got a 68mm conversion neck in my JS7 and got a body from Perle. Had to mod the heel a little and did it a while before I had as much knowledge about it than I do now. It came out alright but I wouldn't recommend Perle again - for what he charges anyway. I've since made a couple necks for both Ibanez neck heel profiles and was going to try some more and some bodies as well. The Hipshots I've had on both my customs built by others have been very nice. Tonally very solid. I had an RG7 with one and the JS7. Highly recommend them.
