Does anyone have any experience with the JLD bridge system. This was originally designed to be installed in guitars that had problems with the tops lifting or swelling bellow the bridge. However according to what I have been reading in actually improves the guitars clarity, tonal range and volume. There are a couple of different models available, one which requires you drill through the bridge and the other which requires no mods what so ever and what appears to be a very simple install. Apparantly Breedlove guitars come with one alrwady installed when new because of the improvement in sound quality. Anyone try these yet. I'm thinking of ordering one for my Guild F50R. They are about $50.00 US.
