    MB112-II Combo

    The MB112-II is one of the smaller amps in Gallien-Krueger's MB Series II range, but it still packs a serious punch! With a 200-watt power amp and ceramic 12" speaker, the MB112-II is a killer companion for the gigging musician used to performing in small/medium-sized venues. It's great for practice too, with its auxiliary input and headphone output letting you 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; great for slap!
    • 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 MB112-II sound bad!
    • USA-Designed Speaker — The special ceramic driver with 2.5" edge wound aluminium voice coil, designed just for this cabinet, is manufactured in the GK USA factory.
    • Lightweight Design — Plywood construction, aluminium chassis, switch mode power supply and power amp deliver 200W performance in a rugged 30lb (13.6kg) package.
    • Contemporary Connectivity — Balanced DI with pre/post switch, aux in and headphone output for silent practice, plus "chain out" to drive GK's MBP powered enclosures (pair with the 112 MBP).
    • Switch Mode Power — Extremely lightweight switch mode power supply and power amp deliver 200W into the speaker with very little wasted heat dissipation.
    • 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.
