Compact and Powerful

The Cube-100 Bass has enough power to drive bass lines through band rehearsals and live gigs, thanks to its 100 rockin’ watts of amplification. And because of the compact design, you won’t be worn out carrying the amp back and forth between your home and gigs.

Renowned COSM Amps and More

The Cube-100 Bass has eight COSM amp models built in, including Octave Bass and the new “Super Flat.” These are all-original amp models from Roland R&D. Octave Bass is an octaver for producing the heaviest and lowest bass sounds. Super Flat responds accurately to a wide sound frequency, from the low-ends to the highs of the bass input, and you get a clean, clear tone that retains the natural sound quality of your bass. Its internal DSP is carefully tuned to avoid excessive coloration of the sound. It’s a great way to get the natural tone of upright basses with pickups.

Onboard DSP Effects

Once you’ve chosen the amp model of choice, route it through the Cube-100 Bass’s stellar digital effects, including EFX (Chorus/Flanger/T-Wah) and independent Delay/Reverb. Optional footswitches can be connected for controlling effects on/off.

Connect and Conquer

Connect directly to PA mixers through the Cube-100 Bass’s Balanced Out and Line Out jacks. With the Balanced Out jack, you can either send your direct bass signal or your customized bass sounds to PA mixers. You can also interface with larger external speaker cabinets through the built-in Ext Speaker jack. When the Cube-100 Bass is connected to an external speaker, the amp models and effects can still be accessed while gaining more power through the larger speakers. It also has a Tuner Out jack for convenient tuner connection. Lest we forget about the studio — the Cube-100 Bass’s Recording/Phones output jack and its variety of amp models make it a great choice for recording applications.
