Simple controls allow you create looped live performances. Onboard looping lets you create interesting layered effects. With the USB connection you can pass tracks to and from your computer. The looping effects also include half speed playback and reverse playback. You can also combine the two modes together to create interesting sonic textures. Five minute record loop with unlimited over dubbing. Please note: This pedal does not come with it's own power supply. I can be operated off any center negative 9v power supply or 1-2 9v batteries. It's a superb looper pedal I've just never had the time to really use it. Mint condition in it's original box. $115 shipped via Priority Mail. Payment via PayPal.
