Roland CUBE-20XL Bass Amplifier

At under 21 lbs., the ultra-portable CUBE-20XL BASS combo amp packs most of the top-of-the-line XL series features into one of Roland's most portable bass amp designs yet. In addition to six fantastic COSM amp models, the CUBE-20XL BASS comes loaded with seven studio- and stage-ready effects, such as drive and poly octave, so you can get really creative. Single-knob compression and drive control gives your tone an edge - this 20-watt amp packs a serious punch! Luckily, Roland also includes a power squeezer function, which let you get wide-open and punchy sound at a volume that's perfect for solo sessions.
