The CUBE-20XL offers two switchable channels: JC Clean and Lead. The Lead channel provides six COSM-powered choices, including Overdrive, Distortion, Metal, Metal Stack, Acoustic Simulator, and the new Extreme. The JC Clean channel provides pure, transparent tone. Channel switching can be carried out from the amp’s top panel or via optional footswitch (BOSS FS series, sold separately).
The CUBE-20XL’s EFX section provides six types of great-sounding digital effects, including Chorus, Flanger, Phaser, Tremolo, Heavy Octave, plus independent Delay and COSM Spring Reverb. For hands-free selection, an optional footswitch can be used to switch the EFX on and off.
Tuner and Aux Input
The handy built-in tuner lets you tune while your guitar is connected to the CUBE-20XL. Manual and Chromatic tuning modes are provided. In addition, the Tuning Fork function conveniently emits a reference pitch if you wish to hear an audible tone. Another useful feature, the Aux Input, can accept a portable music player for jam-along sessions with your favorite songs and backing tracks.
Composite Object Sound Modeling (COSM) is Roland’s innovative and powerful sound-modeling technology. COSM analyzes the many factors that make up the original sound, such as the electrical and physical characteristics of the original, and then produces a digital model that can reproduce the same sound. In designing the CUBE-XL series, Roland meticulously analyzed and modeled array of world-class amps and effects to bring you the versatile and authentic tone palette that these amps provide.
