Going far beyond modeling, Rolands Tube Logic design philosophy starts with carefully reproducing the inner workings of the revered tweed-era tube amp in every way, from guitar input to speaker output. Versatile clean and crunch channels can be used independently or combined for a complex range of tones, while variable output power modes let you dial in burning, full-throttle sound at any volume. Road-tested and fine-tuned with feedback from top players, the gig-ready Blues Cube delivers the sweet, magical tone and satisfying feel that makes a great guitar amp a highly expressive musical instrument. Performance-Ready Amp Ready for live playing, the Blues Cube Artist is equipped with 60 watts of power, plus a custom 12-inch speaker thats been specially designed for maximum tonal response with Tube Logic. The open-back cabinet features poplar plywood construction, which offers acoustically vibrant tone for solo or group performances. Clean, Crunch and Dual Tone The Blues Cube Artist has two independent channels one voiced for cleaner tones, and the other for crunch. Each channel has its own Boost and Tone switches to shape the character. The Clean channels single volume control dials in natural tube fullness and bite as the volume is cranked, while the Crunch channels variable gain control provides a range of grit flavors from mild to aggressive. With the press of a switch, the unique Dual Tone mode lets you blend both channels together for an endless array of rich tones. And just like a vintage tube amp, the Blues Cube loves stompboxes, allowing you to further shape your personal sound by hitting the amps front end with your favorite gain pedals. Wide-Open Sound at Any Volume Every tube-amp player knows that you really need to turn up the volume and push the output tubes to get the amp to sing at its best. The downside is that the sound simply becomes too loud for playing anywhere but the biggest stages though that s certainly never stopped guitarists from trying! With Tube Logic, the Blues Cube authentically delivers the complex distortion characteristics of output tubes and their interaction with the output transformer, with the sound getting richer and the feel becoming more dynamically responsive as the overall volume is increased. But with the Blues Cubes variable Power Control, youre able to enjoy this musical, cranked-up tone while matching the volume to any situation, from recording to rehearsals to nightclub gigs and beyond.
