Between a three-band EQ and a power squeeze, the Roland Cube Base 20XL will be your go-to for those times when you're going to need a rich, smooth and big bass guitar amp that's also extremely portable. These amplifiers remain incredibly portable and travel friendly with enhanced performance that improves upon previous products made in the Cube tradition. Custom FFP, one of Roland's core technologies, and COSM technology allow for maximum efficiency for such a combat body, offering you both the most convenient model in the family as well as a meaty combo of 20 watts, an 8-inch custom speaker, six COSM amp models, pro-quality effects (including Reverb, Solo and Compression), and more.
