A portable 20-watt guitar amp with an 8" speaker and two discrete channels plus Solo boost.


Price: £170.00

The latest addition to the top-selling CUBE amp family (with over a million sold) is the CUBE-XL series. Small yet mighty, 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. The compact size is perfect for practice at home and band rehearsals, 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 setting. 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 jamming, while the onboard tuning fork lets you tune your guitar without un-plugging.

COSM defined

Composite Object Sound Modelling (COSM) is Roland’s innovative and powerful sound-modelling technology. COSM analyses 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 analysed and modelled an array of world-class amps and effects to bring you the versatile and authentic tone palette that these amps provide.
