Boss released the RC-300 Loop Station in the wake of the looper craze, offering a powerful three-track stereo looping system that doubles as an effects pedal, an expression pedal, and even a control panel. The RC-300 functions with any instrument or voice you can plug in, and even has phantom power for mic’d instruments. Up to three hours of internal memory and the ability to transfer loops over to your computer for later use all builds into one powerhouse looping system. Includes power supply
