First introduced in 1976, the StingRay has been revered as one of the most iconic bass guitars in history. The StingRay was the first production four string bass to feature on-board active equalization. The flagship of the Music Man line, today's StingRay is the same as it was some forty years ago featuring a solid roadworthy construction, massive hardened steel bridge, elegant oval pickguard, 3+1 tuning key configuration, and the ever popular Music Man humbucker. All of which combined produce a look, feel and sound that are remarkably unmistakable.
