The Cube Street II from Boss is a battery-powered stereo amplifier for mobile music performers or anyone who needs high-quality sound on the go. Evolved from Roland’s Cube Street — and newly rebranded with the Boss name — the compact Cube Street II features two input channels for mics and instruments, onboard effects, looper and harmony functions and more. The amplifier also includes support for the optional Boss Bluetooth Audio MIDI Dual Adaptor, a new product that lets users wirelessly stream backing tracks and control Cube Street II functions with a dedicated app for iOS and Android mobile devices. The Cube Street II is even lighter and more durable than Roland’s Cube Street, thanks to a modern ABS injection-molded cabinet design.
