    MB210-II Combo

    The MB210-II is a dual-speaker delight! With a 350-watt power amp and two ceramic 10" speakers, the MB210-II packs a hefty punch and has enough headroom to effortlessly fill a medium-sized venue with room-shaking volume. Also boasting built-in boost and limiter functions, as well as a horn for achieving greater top-end clarity, the Gallien-Krueger MB210-II is a must-have for the tone-conscious bassist. Want to practice quietly? With the MB210-II's auxiliary input and headphone output, you can jam along to your favourite tracks in silence.

    Key Features

    • 4-Band Active EQ — Derives from GK's legendary 800RB amp. Provides extensive tone-shaping potential so that you can find the sonic sweet-spot, especially with the 'Hi Mid' and 'Lo Mid' knobs.
    • Contour Control — Completely re-voices the amplifier by tuning between two different shaping circuits, with greatly different responses. When the the control is engaged, the low-end is slightly boosted, the mids are scooped, and the high-end is pushed up.
    • Variable Q — Another feature inherited from the 800RB. This unique design varies the EQ bandwidth to retain a musical response even at extreme settings. In other words, it's hard to make the MB210-II sound bad!
    • USA-Designed Speakers — The special drivers with 2" edge-wound aluminium voice coils, designed just for this cabinet, are manufactured in the Gallien-Krueger USA factory.
    • Boost & Limiter — Attain that legendary Gallien-Krueger "growl" by turning up the MB210-II's dedicated boost control. Engage the limiter to prevent distortion; designed if you're playing anything loud like bombastic slap techniques!
    • Built-In Horn — Switch on the high-frequency tweeter to get some extra top-end spank or "air"; ideal for cutting through the mix.
    • Lightweight Design — Plywood construction, aluminium chassis, switch mode power supply and power amp deliver ground-shaking performance in a rugged 39lb (17.7kg) package. Each speaker is isolated in its own chamber; eliminating tone-robbing standing waves and sound leakage through the cabinet walls.
    • Contemporary Connectivity — Balanced DI with pre/post switch, aux in and headphone output for silent practice, plus extension speaker jack and "chain out" to drive GK's MBP powered enclosures.
    • Switch Mode Power — Extremely light weight switch mode power supply and power amp deliver 350W internally and 500W with an extension cabinet.
    • Critically Damped — The amp's port is specifically tuned for optimum performance, coupled with a particular jute blend of damping material that provides the right amount of damping at certain frequencies.
    • Smart Protection Circuitry — Constantly monitors for unsafe operating conditions such as short circuits, mis-wired speaker cables, blown speakers, improper ventilation, and incorrect speaker configurations.

    Mr aaren jackson9th Dec 2018

    Fantastic combo amp, it sounds nice and warm, yet there's plenty of clarity to it, even without the horn. The EQ is musical even at extreme settings, though I usually leave the bass & treble flat and scoop the mids slightly with the EQ and contour switch. It's a nice compact size and is quite light, and it looks very sleek and smart too.
