Overview

Aggressive distortion and portable design give bassists bold new tones.

The Markbass Little Mark Rocker 58R bass amp head lets you shape aggressive rock tones with its versatile overdrive and distortion. Designed for bassists who want vintage grit and modern power, this 300W amp packs a punch. With the Rocker 58R, you get footswitchable overdrive, a three-way EQ switch for quick tonal changes and Markbass' signature warm, clear sound.

Onboard Overdrive Takes You Into The Red

The Little Mark Rocker 58R gives you crunchy overdrive and distorted tones at the turn of a knob. Select between two overdrive types, then blend in distortion using the drive and blend controls. From light breakup to aggressive snarls, this amp delivers. The optional footswitch lets you engage overdrive on the fly so you can drop into a solo or chorus with ease.

New EQ Provides Tonal Versatility

Shape your core tone using the Little Mark Rocker 58R's four-band EQ with revoiced frequency centers tuned for rock. When you need a quick tone change, flip the three-way EQ switch to "old school" for a vintage scoop or "cut" for an aggressive bump in the lows and highs. The EQ switch's third position is for the optional footswitch, letting you switch EQ presets with your foot.

MPT Power Amp Provides Headroom and Clarity

At the heart of the Little Mark Rocker 58R is Markbass' proprietary MPT power amp technology. Designed specifically for bass, the MPT power amp provides up to 300 watts of power with a sensitive, tube-like response. Notes ring clear and true even at high volumes. Despite its power, this amp remains lightweight and portable thanks to an efficient Class-D design.

D.I. Out and Mute Switch Offer Live Convenience

For live playing, the Little Mark Rocker 58R provides a balanced D.I. out with level control and pre-/post-EQ switching. Send your tone directly to the PA, adjusting the level to match the amp. When tuning or switching basses, engage the mute switch to cut the sound. The Little Mark Rocker 58R's front-panel design keeps all controls within easy reach. Experience the Markbass Little Mark Rocker 58R's aggressive tone and portability for yourself. This amp delivers rock-ready sound in a gig-ready package.
