Featuring a dual alnico-backed humbucker design, five-way selector switch for easy combination toggling and the coveted built-in three-band equalization, the Ernie Ball Music Man StingRay 4 HH offers double the humbuckers for double the pleasure. Big, bold, and unabashed, this classic bass offers an even wider degree of versatility than its single-humbucker cousin for a smattering of lush low-end tones accessible on the fly via a flick of a switch or a roll of a knob.
