Roland has expanded its Cube-GX line of amplifiers with the Cube-10GX. It offers 10 watts output and uses a custom-designed 8″ speaker. Its tones can be customized using the Cube Kit app, which offers 10 COSM amps, including amps for bass and acoustic/electric guitar. Out of the box, the Cube-10GX includes three amp types from the app – Clean, Crunch, and Lead – along with controls for Bass, Middle, and Treble. Its three effects – chorus, delay, and reverb – can be dialed up with a single knob, and the reverb section offers plate and retro spring variations. A rear-panel Aux jack allows connection to a music player or smart phone for playing music through the amp. For more, go to www.rolandus.com.
