Tight, Punchy Sound
The Cube-30 Bass gives bass players loud and punchy bass tones despite its compact size. Using a 30-watt amp and 10-in. coaxial speaker system--with powerful low end and an individual tweeter for clearer highs--this compact amp will knock your socks off! Onboard compression and 3-band EQ let you shape the tone any way you want.

COSM Bass Amp Modeling
Thanks to Roland’s COSM technology, the Cube-30 Bass can convincingly model six of your favorite bass amps--like "Bass360", "Concert 810", "Flip Top", "B Man" and more. There’s even an "Octave Bass" setting which adds a tone one octave below the original note for truly earth-shaking sound.

Onboard DSP Effects
With onboard DSP effects, you can plug in your bass without complicated setups. The Cube-30 Bass includes everything you need: pro-quality reverb and delay, plus essentials like chorus and flanger. There’s even a T-Wah effect for adding a sweeping filtered sound to your tone - great for funk bass.

A Marvel of Convenience
Whether practicing at home or tracking in the studio, the Cube-30 Bass can get the job done. With a 1/4 in. Recording/Headphones output, you can connect directly to a mixing console or to a pair of headphones. A dedicated Shape switch makes it easy to instantly change your tone. Whether for practice or performance, nothing beats the Cube-30 Bass!
