BADASS BASS II I had this installed on my Jazz Bass 20 years ago. Installation and string groove adjustments were done at a repair shop. The head of the height adjustment screw for the 4th string (right side) is stripped. Other than that, it functions without any problems. Bridge mounting screws are not included. This bridge improves sustain and tends to tighten the sound. Instant purchase is OK(^^) I will ship within 24 hours of purchase. I will wrap it simply and ship via Rakuraku Mercari delivery♪ If you purchase with other items on sale, I will discount 200 yen from the total amount. Please comment before purchasing, and I will adjust the price♪
