Gargantuan Gallien-Krueger power and tone in portable packages — that’s the MB Series II for you!

MB115-II Combo

The MB115-II is a portable powerhouse! With a 200-watt power amp and ceramic 15″ speaker, the MB115-II really packs a punch and has enough volume to effortlessly fill out medium-sized venues. Apart from possessing a bigger speaker than the smaller MB112-II, the MB115-II also has built-in boost and limiter functions, as well as a horn for achieving greater top-end clarity. It’s ideal 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.
• 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 MB115-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.
• Boost & Limiter — Attain that legendary Gallien-Krueger “growl” by turning up the MB115-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 — Internal bracing minimises tone-robbing leakage of sound through the walls of the cabinet. Plywood construction, aluminium chassis, switch mode power supply and power amp deliver 200W performance in a rugged 38lb (17.2kg) 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 115 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.
