Markbass Little Marcus 58R
INTRODUCTION
The new LITTLE MARCUS 58R is ready to replicate the worldwide success of our Marcus Miller signature heads, we introduced few years ago. It is the result of the meeting between Marcus Miller — renowned for his groundbreaking style and trademark sound— and MarcoDe Virgiliis, considered an innovator, being the first pioneer introducing lightweight, portable, powerful and great sounding bass heads and cabinets.
As for the previous version, it has an amazing warm and natural sound, clear definition, punch and dynamic, respecting the priority of tone like all the Little Mark heads, plus a new tone setting with 5-band EQ on EQ1, from ULTRALOW to HIGH and the two new Old School and Millerizer filters featured on EQ2 taylored together with Marcus, allowing to quick obtain a vintage tone or an amazing slap sound. The new bi-band limiter featured on this amp responds faster and more dynamically to your playing. It’s paired with a 500W power amp, providing impeccable bass frequency reproduction thanks to our MPT proprietary amp specifically designed for bass.
The new LITTLE MARCUS 58R amp new design features all the connections and controls on the front panel leaving on the rear panel only the speaker outs and AC power socket, offering optimal ergonomics and making everything more practical. All in an high build quality and ultralight new chassis for a super portable package that weights only 2,17Kg / 4.78lbs.
