One of the best sounding amps I've played

I did tons of research to find the perfect amp that fit my price range and that delivered the amount and quality of sound that I needed.
This amp has never ceased to amaze and deliver. I've played it with pop/rock groups, jazz bands, in the studio rehearsals. Don't be deceived by the small size, this amp has enough volume to handle almost any gig. Even if you're playing in a big venue it's got direct out, so there's no reason that this amp can't be your all-purpose amp.

Best Bass Combo Amp For The $$

By far the most powerful, pure, floor thumping bass combo amp I've ever played through under $1000. At $699 list, still the best bargain out there for live performing output. Earlier versions had tweeter issues (which were corrected immediately by GK's excellent customer support system) and this unit should be your choice, hands-down, if you are looking to blend budget with performance.

A great amp for the price

Bought this amp for my son. A fabulous light-weight amp with tons of power. Had to adjust the settings to get the hiss out of the amp. (mostly in the high end.) It's a great amp for gigs in different kinds of situations. Very happy with it, especially for the price!

Great Balance in a Combo

I really like this amp. Great balance of price, power, and weight in a combo. The sound is clean and does not require pristine power supply to stay that way. The rig has enough punch to cut through everything else on stage, including heavy-handed drumming. The price is reasonable, and the light weight is easy on the back. I've used it in venues large and small, indoors and out. Works very well with my J-bass, A/E bass, and electric upright. Downsides? The first one out of the box didn't work at all, and I had to get a second. The XLR Out is in a bad location. Sound techs need a flathead screwdriver to extract their cables.

Back saving gig workhorse with mojo

I picked up the MB212 because I was tired of waiting for RME to release the BabyFace (of which I was already paying on). I've had the combo for about 3-4 weeks and it has been used at over 10 gigs in taverns, brewpubs, restaurants and a theater this month. I've used it primarily with my Upton Bass that has a K&K BassMax pickup; also my PJ Warmoth & Guild acoustic bass. It has a good sound. If you're not used to D-Class amplifiers you might be startled at how high you have to turn things up, but it's clean and has mojo.

Too Good To Be True -- And Is!

Touted as a great amp at half the weight, only the weight part is correct. This amp has no sustaining "thump" or drive. It seems to peter out early and any major push of volume creates crackling and a feeling that the cones are ready for the grave. Very disappointed in view of all the hype this model was given. The weight is an advantage however and if you are old and don't ever play past "3" on the volume dial, this amp might be for you.
