The Gallien-Krueger MB112-II 200W 1x15 Ultralight Bass Combo Amp is an addition to GK’s legendary MicroBass Series. It delivers a big sound from a light, compact package. At 200-watts the MB112-II has the power to be heard in any situation. It's designed with preamp tone-shaping circuitry that feeds into a lightweight Class-D power amp. The preamp uses GK's 4-band active tone control section with a Contour preset feature. There are both Passive and Active bass inputs and a defeatable Limiter for controlling your sound. The 12" Paragon speaker is extremely sensitive and makes this amp surprisingly loud. The horn tweeter can be engaged or not to suit different playing environments or to further shape your sound. An 1/8" Aux. input and headphone jack allow for silent practice along with an MP3 player or other sound source. An XLR DI output is included for recording or live sound reinforcement.

Standard tone controls and graphic equalizers give you plenty of variation, but they don’t provide what the instrument really needs. The fact is, graphic equalizers are intended for room equalization. The equalization in Gallien-Krueger amplifiers reflects 40 years of continuous development and refinement. The GK equalizer is unique to the industry, it’s not just a normal four band equalizer, each section is a special circuit optimized to perform a Bass specific job in its range of operation. These sections are wired in series, adding to one another, to create a tremendously flexible equalizer that sounds natural at any setting. Now it is possible to obtain the sound you desire.

The Contour is used to complely revoice the amplifier by tuning between two different shaping circuits, with greatly different responses. With the control engaged, the low end is slightly boosted, the mids are dropped and the high end is pushed up.

The limiter is designed to detect signal levels at the input of the power amp that cause unwanted distortion. It attenuates extreme peaks to allow high volume output while maintaining signal integrity.

“G.I.V.E.” Technology
The Gallien-Krueger MB210-II, MB115-II and MB212-II pre-amps incorporate G.I.V.E (Gate Induced Valve Effect) Technology. Field effect devices are used with the gate biased in a way that emphasizes the optimum harmonic content of the signal. Working in conjunction with the unique four band active equalizer and contour, G.I.V.E. technology produces a consistently pleasing bass tone.

Bass Amp Shoot out!


Hello-A'm using this Bass Amp practice for Studio Recordings but I end up using my $4,000.00 Neve Channel Strip for it's DI input to track my recordings. This Amps is great for all fequencies responses from a Active Bass Guitar. I bought 3 Amps Fender Rumble, Peavey Mx1x12 7 & the GALLEN KREUGER 12" .... which may not come with all Bells & Whistles but delivers tonality.

Unbelievably Good


This amp is amazing. I was looking for a lightweight powerhouse, and this it. Definitely loud enough for rehearsals and small to medium gigs. Large gigs need a PA system anyway - I'm glad the days of spine-crunching bass amps just to be heard are behind me. The tones I can dial in with this amp are heaven - clear - and organic sounding (so many bass amps just sound blah and artificial). This amp sounds like an extension of your bass. Really happy bassist here :)
