The black Cube Lite Guitar Amplifier from Roland is a 2.1 channel audio system designed to allow you to play along with and record to your iPhone, iPad, or iPod touch. A pair of three-inch stereo speakers and a three-inch subwoofer produces 10 watts of total output. If you need to practice silently, the Cube Lite has a 1/8" headphone jack that mutes the speaker output when in use. Featuring Roland's COSM amp modeling technology, you can select your desired tone from built-in JC Clean, Crunch, and Extreme settings. The Cube Lite connects to any iOS device through its i-Cube Link input and included four-pole mini cable. With the free CUBE JAM app, you can play along with your own tracks, or record directly to your iDevice. You can also use the Cube Lite as a playback device for your digital music library when not jamming.
