The GR Bass AT Cube 350 is one of the most impressive examples of how far modern bass amplification has come. Built around GR’s carbon fiber construction, this combo delivers serious power and clarity in a format that feels almost unreal the first time you pick it up.

At its core is GR’s “Pure Sound” philosophy. What you get here is a fast, immediate response with incredible detail and headroom, allowing the natural voice of your instrument to come through without coloration. It’s tight, punchy, and articulate, with a low end that stays controlled even at higher volumes.

Despite its compact footprint, the AT Cube 350 is more than capable in real-world situations. From rehearsals and studio work to club gigs, it has the volume and projection to keep up while remaining one of the most portable 1x12 combos on the market.

It’s a perfect solution for players who want professional performance without the weight and bulk of traditional rigs.
