Just as the CUBE guitar-amp family received an XL upgrade, now it's time for the CUBE BASS line to reach XL status. The CUBE XL BASS amplifiers remain portable and travel friendly, a CUBE tradition, but they benefit from new-generation XL performance enhancements. These new amps deliver a knock-out punch with custom FFP and COSM technology. FFP is one of Roland's core technologies in which each component — amp, cabinet, and speaker — achieves maximum efficiency and performance for incredible power from a compact body.

The most portable of the family, the CUBE-20XL BASS, features 20 watts of power, an 8-inch custom speaker, six COSM amp models, pro-quality effects (Reverb, Delay, Chorus, Solo, Poly Octave, Compression, and Overdrive), Power Squeezer for big sound at low volume, and 3-band EQ.


  • Ultra-compact 20-watt bass amp with custom-designed 8-inch speaker
  • Six COSM amp models onboard
  • Seven effects, including DRIVE and POLY OCTAVE
  • POWER SQUEEZER for big, rich sound at low volumes; great for home practice and other volume sensitive environments
  • Three-band EQ for fine-tuning your sound
  • Built-in bass tuner

Excellent amp


Excellent practice amp with options to adjust tone



Great little amp!


This is a nice little practice amp, probably not powerful enough for gigging with a band, but mine easily kept up with 35 ukuleles at our weekly sessions. Lots of tonal variation with the eq and the amp simulators, and typical high Roland build quality make this one a keeper. I also have the bass cube 100 and a MicroCube, so this fits in nicely with the rest of the stable. The first time I used it publicly, I had numerous positive comments about my tone. And it's very lightweight. Definitely a keeper!

Perfect practice amp


I use this amp for home practice, with or without phones. There's plenty of sound adjustment and the amp is loud enough for playing at home to a drum box or an mp3 player. The quality of fabrication is what you could expect from Roland: Solid, nice, easy to read and use.
