Mark Bass Little Mark Rocker 58R 500W / 300W Solid State Bass Amp Head

Aggressive 500W Bass Head With Blendable Drive and Portable Control

The Mark Bass Little Mark Rocker 58R is a 500W bass amp head designed for players who want Little Mark versatility with a more aggressive onboard drive section. Its solid-state preamp and MPT power amp deliver 500W at 4 ohms or 300W at 8 ohms, giving bassists a compact head with enough output for rehearsals, live work and direct-to-PA setups.

The drive section is the main tonal difference compared to other heads. A dedicated Drive control moves from crunchy overdrive to more aggressive distortion, while the Type 1 and Type 2 switch offers two drive characters. The Blend control mixes clean and distorted signals, so players can add grit while keeping low-end definition and note weight intact.

The 4-band EQ is tuned for bass tones that cut through a mix, with Low, Low Mid, Mid High and High controls for detailed shaping. A 3-way switch offers Old, Cut and footswitch modes, while the Old School control rolls off a widening range of frequencies for a more vintage-style response. Front-panel connections, mute, DI level, pre or post EQ switching, send and return, and optional footswitch control keep the workflow practical.

At Riffs & Licks Music, we think the Little Mark Rocker 58R is ideal for bassists who want a lightweight amp head with real drive flexibility, strong clean fundamentals and fast access to stage-ready controls.
