It’s extraordinary to think that the first Roland Cube guitar amp dates as far as back as 1978, and since then there’s been over 50 versions, each promising high-quality tones with unparalleled portability for the guitarist on the move. 

In 2021, with the introduction of the Cube Street II, the series was switched over to the Boss line – a sensible consideration given the brand’s guitar-centric legacy. The newest addition to the family is the Dual Cube LX, which offers more controls and features than any of its predecessors in a desktop amp format.
