Used item. This is a 1980s YAMAHA locking bridge. It's the 1st model of the YAMAHA Rocki'n Magic series. This is a YAMAHA original bridge with a unique design, a hefty weight, and a distinctive mechanical structure. - Strings are inserted from the rear of the bridge without cutting the ball end, and locked with a cover. - Octave adjustment is possible with the screws at the rear of the bridge. - Weighs a hefty 478g, a rugged and robust bridge. - The block uses a steel block, which is acoustically advantageous. The fine tuner knobs have been changed to stainless steel, and the 5th string knob has been replaced with a larger one. Please check the photos for the condition.
