I've used these on a couple builds so far, and I love them. Not only do they cover up any "slop" due to some of us routing our pickup cavities in our box lids with a simple dremel tool (and no templates), but they also help with the placement of the pickups if you use them to position and mark your pickup locations AND the end-result looks fantastic. I've done a couple boxes with no pickup mounts, and they look fine, but these rings add a little class, taking the appearance of my build to a swanky new level. No, I won't use them all the time, but I most certainly will use them on the builds I want to impress with. They're mean, clean and perfectly cut. I will always keep a couple of these on-hand at any given time.
