Old Blood Noise Endeavors AB/Y SWITCHER utility pedal

READ THE OFFICIAL OWNER'S MANUAL HERE. Old Blood Noise Endeavors' description of the Old Blood Noise Endeavors AB/Y Switcher utility pedal   COMBINE AND CHOOSE YOUR SOURCES WITH TWO SWITCHES. Our AB/Y Switcher is a classic for a reason. Use two footswitches to independently connect A or B to Y, or both A and B to Y at the same time. This passive circuitry is commonly used to switch between instruments at the start of a signal chain, or outputs at the end. AB/Y can pass signal without power, but the LED indication requires a 9V DC center negative 2.1mm jack power supply capable of 10mA (not included).
