Small Bass Amp, Big Sound

The Gallien-Krueger MB150S-112 combo bass amp has long been known as a favorite among many of the biggest session players in the music industry. This compact amp, part of the MicroBass series, has big tone and a very flexible EQ, so you can dial in your desired sound. Even though the MB150S-112 is small in size, it is extremely durable and ready for the rigors of the road. An XLR direct output, a line output, and an effects loop ensure you are ready for any situation.

Gallien-Krueger MB150S-112 Combo Bass Amp at a Glance:

  • Big sound and powerful tone controls
  • Solid construction and durability
  • Extremely functional

Big sound and powerful tone controls

The 12" speaker pumps out 100 watts of power, and if you need more you can hook up an extension cabinet for a total of 150 watts out of the MB150S-112. This isn't a wimpy little 150 watts - this is a surprisingly loud and defined sound. The active 4-band EQ lets you dial in the exact tone you are looking for quickly and easily. To further sculpt your perfect sound, Gallien-Krueger has included an adjustable contour and high boost contro and a low cut button. Dial in your tone and start playing.

Solid construction and durability

Gallien-Krueger has been long known for their great-sounding amps. The MicroBass series is one of the standards for high quality compact bass amps (and by compact we mean it only weighs 26 lbs.) The amp chassis is made from sturdy, welded aluminum that is durable enough for the roughest of tours. The MB150S-112 combo will give you years of faithful, tone-filled service.

Extremely functional

As a gigging musician you need to be flexible and have gear that is flexible, too. The Gallien-Krueger MB150S-112 is ready for pretty much anything. An effects loop lets you utilize your favorite pedals after the EQ section of the amp. An XLR direct out sends your signal out pre-EQ, and has a ground lift switch. A 1/4-inch line-out sends a line level signal post-EQ that can be used with a direct box or another power amp. The MicroBass also features a headphone out jack for silent practicing.
