Just over a decade ago, Marco De Virgiliis started pioneering small, lightweight amps; the Markbass Little Mark heads started a new era in bass amplification, inspiring many other companies to follow their lead. You'll be amazed that such a warm, rich and “explosive” sound comes from an amp smaller than our groundbreaking Little Mark heads! And—despite its small size—the Big Bang is packed with extra features that customers have been asking for: aux in, headphone output with level control, plus mute and VLE and VPF filters with footswitch control. Other features, already appreciated by Little Mark users, include a simple and effective 4-band EQ, effects loop, and level control and pre/post EQ switch for the XLR DI output.
