Description
Classic British rock tone, inspired by tones from the ‘60s and ‘70s.
This speaker has a personality all its own, with balance from top to bottom and rich harmonic complexity. Good punch and definition in the lows that won’t get flabby, a warm, throaty, and broad midrange, and nice grit with soaring articulation in the highs.
