Ready to make your volume control a surround sound experience? Check out the Ernie Ball 6165 Stereo Volume/Pan Pedal. A passive pedal built with a dual potentiometer and 500k ohm resistance, the effect sports a switch for toggling between volume and pan modes along with A and B input/outputs which accept both mono and TRS cable types. Capable of functioning as a straight mono volume pedal when wanted, the real attraction here is the room-swallowing stereo swell which submerges your audience in a sea of sound.
