CUBE-20XL: Guitar Amplifier
Compact and Feature Packed
Features
With over one million CUBE amps sold and going strong, Roland continues to push the envelope with innovative amp technology and design. The latest addition to the top-selling CUBE amp family is the CUBE-XL series. Small and lethal, the 20XL is an affordable yet powerful new member of the XL family. The CUBE-20XL delivers 20 watts of output through a high-performance 8" custom speaker. Its compact size is perfect for at-home practice and band rehearsals alike, and is conveniently portable. There are two discrete channels, JC Clean and Lead, plus Solo mode for extra boost. Six BOSS Lead types are provided, including the new Extreme. Nine effects are onboard, including Heavy Octave, COSM® vintage Spring Reverb, and Power Squeezer for full gain at low volume. An Aux Input allows portable music players to be connected for jam-along fun, while the onboard Tuning Fork lets you tune your guitar without unplugging.

Dual Channels
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).
Pro Effects
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.
COSM® Defined
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.
