ABM / ABM5050V Modern High-End Vintage Tremolo / Narrow String Spacing 5050V: Vintage Mount Hole / 56.35mm (2 7/32"), Wide String Spacing ※This is a vintage-style tremolo unit with the same dimensions as classic Stratocasters, etc., with a 56.35mm spacing between the 1st and 6th strings at the center of the six-point mounting screw holes, and a 56.35mm string spacing. The ABM 5050 is a modern, high-end tremolo unit that also inherits the vintage style. At first glance, it looks like a normal tremolo unit, but by carefully optimizing the hidden parts, a "tremolo master" that creates the best sound has been completed. While inheriting the classic vintage design, it achieves the highest peak sound of today. The new generation block with the newly developed "Advanced String Guide" keeps the tremolo unit's tuning proper. The base plate and mounting screws are made with the same hardness, minimizing wear caused by differences in materials when the tremolo unit is moved. ABM's premium vintage saddles have the resonance of the original saddles while also providing excellent tuning stability. It achieves a tone closer to the vintage style than saddles that seek tuning stability in many modern styles.
