Gallien-Krueger MB112-II Bass Combo Amplifier

Gearank Recommendation

The MB112-II first appeared on our recommended list for Combo Bass Amps Under $500 in August 2018 where it remained until a price increase made it ineligible in July 2019.

Then in October 2021 we expanded the price range of the guide to include amps up to $1000 and the MB112-II's high ratings earned it a spot on the new list where it remained until September 2022 when it was out-ranked by the Fender Rumble 200.


Gallien-Krueger amps are well received for the simple yet effective tone shaping features they provide.

The 200 watt MB112-II is their best rated offering in the sub $1000 range, carrying with it the company's "contour" button for a good scooped sound, along with its 4-band EQ controls that are tapered specifically for bass guitars.

At 200 Watts, the Gallien-Kruegger MB112-II is loud enough for stage use, and if that's not enough, it can be paired with compatible GK powered speakers for even more volume.

Finally, all its power and features are packed in a relatively light 28 lbs combo profile.

Although this was previously on our recommended list, there are now models with higher ratings which you can see in our guide to The Best Bass Amps - Combo.
