Plug in two instruments and switch between them without unplugging.
In addition is (2) loops for bypassing your tone sucking effects.
LEDS: For the 9V DC Jack, these units require a 9V AC adapter with a Boss/Ibanez style 2.1mm barrel plug. If you do not have one, we have these in the "Accessories" section. (Unit will work without LED's. The LED circuit in any loop-Master unit does not affect tone.)
DIMENSIONS: 4.7" X 3.7" X 1.18"
