A great-sounding, affordable non-valve amp What? Roland Blues Cube‘Hot’Combo Where seen? www.gear4music.com Price? £419 Description? I’ve played and demoed several models in the Blues Cube range and genuinely like them. Using Roland’s Tube Logic technology, this 30-watt combo looks purposeful in black, and at just over 400mm square and weighing a paltry 12.6kg, it’s small and light enough to carry in one hand with a gig-bag slung over the other shoulder.These things really do sound convincing, and with onboard reverb, plus switchable Boost and Tone features, it offers a range of cool sounds from crystal clean to mean and meaty. Particularly nice touches are power scaling from 0.5w through 5w, 15w and full power, and a USB port for recording direct to computer. It can handle small gigs but would make the perfect practice and demoing buddy.
