I just got a used American Ultra (Texas Tea) on eBay. It arrived with a floating bridge. The seller said he got it at the Chicago Exchange who “set it up” for a beginner player, although they told him it “wasn’t a complete set-up.” I took off the back plate and tightened the two screws holding the metal piece that the springs are hooked onto until the bridge sat down touching the body. Questions: Do Ultras normally arrive new with the floating bridge trem? And, did I do right to tighten the bridge down? Thanks.
