Bought this Babicz Bass Bridge for my Fender USA Jazz Bass, which is string through the body. Fitting was surprisingly easy, with the old bridge coming off and the Babicz screw holes fitting exactly in the same place. It looks and feels solid and good quality. Setting up the bridge saddles was easy with the provided instructions. I also took the opportunity to set up intonation and action whilst setting the bridge up. (Google was my friend for this!). I would recommend this to anyone with a Fender USA Jazz wanting to upgrade the bridge, and those wanting a Badass bridge - these Babicz bridges look and feel the same quality, if not better. Very happy with this purchase. Delivery was the usual standard as expected from Thomann, I love the tracking alerts.
