GK MB212-II

Great Amp with a lot of power. Tone control and ability to create the "growl" that is distinctive is easy! Consulting with Matt Fawcett on the right amp really paid off. Everything about this amp is first class!

Gallien-Krueger MB212-II -2x12" 500watt bass combo

Totally impressed. Fills the room inside and out with a full sound. Used it at a outside show with at least 10,000 people and it kicked butt. Thank you.

HAMMER TIME

This rig will handle any venue. I also teamed it with the powered extension cabinet for 1000w. I'll probably never need quite that power, but an old friend once advised me to get the biggest and best that I could afford. I've applied that to most any purchase I've ever made. I've never regretted it. I can haul this amp and my electric upright bass in one of the smallest Toyotas ever made. The amp has a "punch" and a very warm tone. At about 40 pounds there are no issues with weight. With the strength, power, and warm tone, I would call it "THOR'S VELVET HAMMER".
5/5

Very punchy amp with loads of volume and low end

This amp really did blow me away from the very first time I plugged in! It is easily the loudest combo amp I have ever owned. And I have had many since 1969. I needed a light combo amp to take to practice and to handle small gigs. I play 5 string basses and it handled everything below E extremely well and produced clear mids and nice warm highs as well. I used it in practice last night with my band which takes place in a large shop. Everyone could hear me clearly. I couldn't turn it up a lot or I would have been assaulting our ears. This combo is much better than I expected. You won't be disappointed.

Stellar Combo Rig

When I went to Sweetwater, I took my Stingray 5 with me and tried every amp on display in the bass room. My criteria for choosing an amp were simple. I wanted to be powerful, portable, affordable and have great tone. The GK MB212 II did not disappoint. It was the clear winner an all accounts. Certainly there are more expensive options, and some of them sounded great too, but they fell short in other areas of my search criteria as well (cost/weight). The MB212 is simply thunderous. You don't believe that a combo amp weighing only 40lbs can produce such massive tones. My bandmates couldn't believe it either. We rehearse rather loudly, playing hard rock with two guitarists and a drummer. This amp provided plenty of clear, punchy volume with headroom to spare. Amazing! It's worth noting that this is a new idea in combo amps. The internal 500W power amp is dedicated solely to the speakers within the cab (so you get the full 500 without having to add a cab). Adding a MBP212 extension cab is simple (via a reg mix cable) and doubles the power to 1000W because each extension can has its own internal power supply. A very cool idea! However, I can't see really needing it, because this combo is very loud, and efficient. It's an all around great deal for an American made product. I highly recommend it!
