We must admit, when Roland told us they want TonePedia to demo their pedals with the Blues Cube Artist as the vintage "tube" alternative we were skeptic. Once we set the Blues Cube in the room, mic'd it and hit the record button we were simply astonished. This amplifier does sound, act, feel like a tube amplifier! It sounds amazing. The magic in the Blues Cube Artist is called "Tube Logic". With it, Roland replicates every stage of the much beloved tweed-era tube amplifiers. Thanks to two completely independent channels, you can switch between clean and crunch channels, with each set to your tone. And if needed, you can even set the output to your linking, from stadium worthy 80 watts to bedroom friendly 0.5 watts.
