A Pint-sized Rocker with a Big, Bold Attitude
Armed to the teeth with hard-hitting grit and grind, the Markbass Little Mark Rocker 58R is a compact bass head that threads the needle between all-out aggression and genre-defying flexibility. This muscular bass head begins with the brand’s custom-designed MPT (Mark Proprietary Technology) power section, voiced for high headroom and a pure, clear tone that enhances your instrument’s inherent character. Two distinct overdriven flavors are available via the flip of a switch, with intuitive Drive and Blend controls to take your signal from a subtle bite to gain-drenched fury. Next, a 4-band EQ offers straightforward tone-shaping, bolstered by an Old School filter and a Flat/Scooped/Footswitchable (FSW) switch for dialing in your overall sonic character. You also get a Mute switch, along with a Line Out level control, joined by Pre EQ/Post EQ and Ground Lift switches. Beyond that, this amp’s minuscule footprint ensures that you’ll always find room — even on the most space-challenged rigs. Portable, versatile, and ready to rock, the Markbass Little Mark Rocker 58R does it all with space-saving convenience and raw, driving attitude.
Custom-designed MPT power amp
To ensure optimal low-end performance, Markbass amplifiers come equipped with a proprietary MPT (Mark Proprietary Technology) power amp designed by the brand’s founder, Marco De Virgiliis. This high-headroom power amp was purpose-made to supply an authoritative output with sharp definition and a lively, dynamic feel. Above all else, the MPT is a testament to Markbass and Marco's uncompromising commitment to supplying professional musicians around the world with superior bass tone.
Ample I/O for the stage and studio
The Markbass Little Mark Rocker 58R’s robust I/O section stands at the ready to take on any gigging or recording application with plug-and-play simplicity. Perfect for bassists with a sprawling stompbox collection, this head’s front-mounted effects loop optimally integrates all your favorite pedals. Next, you get an XLR Line Out with a transformer-equipped design to fight off any distortion or unwanted noise introduced by extreme transients. And when it's time to plug into your favorite cab, the Markbass Little Mark Rocker 58R’s speaker output section boasts a heavy-duty speakON jack for a lock-tight connection.
