Enjoy looping two synced stereo tracks and then processing your loops with the power of a multitrack USB recording interface -- all right at your feet. The Boss RC-30 captures signal coming from an instrument or microphone and allows you to loop it back, build on top of your loops, adjust mix volumes, and add effects. Once you've perfected your creations, you can store up to three hours' worth of loops in 99 different memory slots or back up loops on a computer.
