The Little Mark's international success is driven by its versatile sound, suitable for all styles of music. It's also an amp chosen by ROCK bassists, so we decided to make a more aggressive version – adding custom designed and footswitchable drive circuitry for a wide range of onboard overdrive and distortion sounds. And just like our other amps in the 58R series, the LITTLE MARK 58R ROCKER's new design features all the connections and controls on the front panel, keeping a clean rear panel with only power and speaker connectors – this offers optimal ergonomics making everything more practical, all in an ultralight, high build quality chassis for a super portable package. DRIVE AND BLEND CONTROLS: Rock bassists love Little Mark heads, however the awesome drive section of this new model makes the Little Mark 58R Rocker better than ever for rock! The amount of drive, ranging from crunchy overdrive to aggressive distortion, is controlled by the DRIVE pot and a switch allows you to select between two types of drive. The BLEND control mixes between CLEAN and DISTORTED sounds. NEW EQ SETTING / 3-WAY SWITCH / OLD SCHOOL: The 4 Band EQ of the Little Mark 58R Rocker has new centre frequencies which are all tuned to offer a balanced tone that slices through the mix. It also features a 3 way rotary switch that dial in 2 useful EQ presets to quickly select a true FLAT setting, or a CUT setting that has boosted low and highs with scooped mids. The third option on the switch allows you to use an optional Dual Footswitch to control the DRIVE/BLEND section or the CUT EQ preset. The OLD SCHOOL control cuts a wider and wider range of frequencies as you dial it up to easily shape an old style vintage tone.
