Take On Any Stage with Markbass's Flagship Bass Head
The Markbass Little Mark IV builds on the legacy of its stage-proven predecessors with a suite of performance-minded upgrades, providing you with uncompromising tone in a compact head. 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. Gain, 4-band EQ, and Master volume controls offer straightforward tone-shaping, bolstered by an Old School filter and a 3‑way Flat/Scooped/Footswitchable (FSW) switch for dialing in your overall sonic character. Additionally, the Little Mark IV features an Old School knob to warm up your signal and a fast-response bi-band limiter that provides greater dynamic control and natural-sounding high‑frequency clarity — even when you crank it to the max. 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. Put it all together, and it’s abundantly evident why Markbass’s flagship Little Mark IV has won a star spot in the rigs of performers and recording musicians around the globe.

Ample I/O for the stage and studio

And when it's time to plug into your favorite cab, the Markbass Little Mark IV’s speaker output section boasts a heavy-duty speakON jack for a lock-tight connection.
