Wow, this thing is so light! It weighs less than most companies 50W amps. It has a nice full sound due to the 15" speaker. The controls are simple, but effective. The push buttons on the Contour, Limiter and Horn On/Off are a great idea. It's not as flexible as a 100RB, but I think they were going for a more simplified "Practice Amp" motif. The AUX in is a great idea as is the headphone jack. I tried a few active and passive basses through it just to see what kind of tones I could get. I was able to get high quality sounds out of each bass I tried. For only 200W it is very loud and blows away other more expensive amps that I won't name that, supposedly, have more power. It actually kind of shocked me A/B'ing a few amps. GK must have a louder watt measurement than brand X, Y and Z. Bravo to GK for using real poplar plywood for the box instead of the cheaper and heavier particleboard. Only one beef, the grill rattled a little bit, but it just needed about half a turn on a screwdriver to fix it. No biggie. If I ever get in the market for a new combo amp, it will be this guy for sure.

I've waited a while to do this review- I don't like knee-jerk reaction reviews. I bought one of these several months ago to take on a gig 220 miles away in the middle of nowhere. It sounded great in the store, but when I got to the gig, IT DID NOT WORK AT ALL! Needless to say, I was not pleased. I called my salesperson at GC, (who I love, by the way- she's a real sweetheart!), but I had to read her to riot act. Thankfully, I was able to go through my sansamp into the board, so the show went on, but I gnashed my teeth all the way through. Once I got back home, she was able to get me a replacement on the spot, although I was hesitant to get another. Like other reviewers, I bought it for its weighing next to nothing. I like the fact that it moves a lot of air, and the basses I play, (Rick 4001, Marcus Miller, Telecaster bass) all sound great. On the down side, I've only had it for a few months, and the tolex(?) has started to come away from the unprotected corners. Bad glue, perhaps? Since that gig experience, I've only played it in my studio, not wanting to chance another occurance, so it hasn't been abused. I have an Acoustic B200 head with a Neo 2-10 cab and 15 cab, and it blows this away. I thought the GK's light weight would be a good idea for gigging. It is, but...

Comments about Gallien-Krueger MB115 1x15 200W Ultralight Bass Combo Amp:

To all the bass players out there, if your looking for a great sounding, yet light package sound system to carry in your vinues, this amp is for you. I already own one of these combo amps. My first experience with GK equipment was when I was playing at a visiting church and they had a GK 1001 amp with a 4-10 speaker cab. I was totally blown away how good this setup sounded. That's when I went to my local GC dealer and saw this MB 115 combo. I loved the light weight and great sound. I play for my church and other gospel venues, some with rather large sanctuary's. There hasn't been a location that I haven't been able to handle. Recently I was looking at other, larger GK systems because I want to keep one combo at the church and another one at home so when I'm called to play at other functions, I have a combo with me at all times ready to go. One thing I want to try is, if I'm in a larger hall, to run a splitter from my bass cable to each cabinet stacked up. I would think that would sound awesome. Overall, I've been very satisfied with this combo and look forward to getting another one. I will let you folks know how stacking both cabinets works out. Until then, keep Thumping!!!!!

Excelent Bass Amp

By 

from bloomington, illinois

Comments about Gallien-Krueger MB115 1x15 200W Ultralight Bass Combo Amp:

I am very impressed with this amp. I was suspicious of the quality due to the size and weight but was blown away when i played it in the store. After taking it home i was even further suprised when i got into the tweaking of the amp. I have been playing bass for the last 10+ years. I play a Hohner B-bass Professional with active pickups. I replaced my Peavey Max-160 head and 500 watt, single 15" cabinet with the GK MB-115. This amp delivers clear, deep bass tones and still has the clarity to be heard without the tweeter ingaged. The tweeter cleans and brightens up the sound nicely but does not take away from the nice thick tone. The contour switch is a nice touch as it thickens the tone a bit and adds a little chimey overtone. With seperate gain and volume knobs the sky is the limit with the volume. And the boost knob engages the beautiful GK growel that GK can offer. I have played a GK 700-RB2 with an Ampeg 4x12 and this amp is the closest i have come to getting that sound back and at just a fraction of the cost and weight. This is an excelent amp! If you are looking for a smaller amp but dont want to lose the tone and power of a large amp, this is your amp. I am very picky about my tone and GK is the only brand i have ever been fully satisfied with. You can play any style of music with this amp. This amp is solid!! I highly recomend it.

Best Combo you Can Buy for $400

By 

from VA

Comments about Gallien-Krueger MB115 1x15 200W Ultralight Bass Combo Amp:

I played every combo I could find in the $300-500 range at a few different stores before deciding on this one. The MB115 sold me mainly on its clarity. The light weight was a close second. I originally got the amp for practice with my band (4-piece rock/metal, practicing in a basement). More than enough volume for that. I then tried it at a gig in a small bar, and was pleasantly surprised to find it had plenty of power for that as well, even without being run through a PA. I was somewhat concerned that the light weight meant cheaper quality components, but after about 100 hours on the amp, I've had no issues. As far as sound quality goes, I won't pretend it's on the same level as a higher-end tube amp, but it's also not going to embarrass you. The frequency output is a bit "scooped" - it's somewhat biased towards the low and high ends of the spectrum. At the same time, the midrange is adequate to make the sound balanced in a live environment. Let's face it, for the vast majority of gigs you're going to play, you mainly just need a consistent volume level throughout the frequency range, and that can absolutely be accomplished with this amp with a minimum of attention to settings. About the only issue I've had is the excessive hiss from the horn when it's activated, which has been mentioned in other reviews. I leave the horn turned off, and there is still more than enough high end without it. In fact, the high end is actually pretty impressive in terms of clarity, especially for a 1x15. As for the contour and limiter functions, I leave them off. My sound is better without the contour shaping, and I don't have a need for the limiter. My instrument has passive pickups but an active EQ, so YMMV. At this point, I really don't see any reason to spring for a more powerful rig. Smaller venues are totally turn-key - just plug in and play. Larger venues would be run through a PA, so really nothing to worry about there either. Given that I'm not going to be playing venues much lager than a large bar, this is pretty much the perfect solution. You might get a couple of sidewards glances from the gear snobs, but you can laugh at them as you use one hand to load out the amp that just did the same job as their $1500 tube setup.

Versatile, light and loud

By 

from Chicago, IL

Comments about Gallien-Krueger MB115 1x15 200W Ultralight Bass Combo Amp:

I like this amp a lot. The tone is excellent, the combination of gain and volume, plus a 4 band eq, PLUS the boost control (which works like an overdrive) gives you a lot of options when creating a sound that fits you. The boost is touch sensitive so you can set it in the middle and it'll only bite if you dig in, you can get clean and distorted tones without having to change settings. It's very lightweight *for a 200 watt 15 inch combo*, meaning it's not ULTRA portable. It actually looked and felt smaller in the store, weird how that happens. It's very portable but it's not tiny. I've found nothing wrong with this at all. Even the tweeter sounds good and I've read a lot of reviews that said it didn't. Maybe they fixed that issue, because mine sounds really clean. It gets plenty loud, like wall-shaking loud, but can pull of a good tone at low volume which was key for me. Best all-rounder I could find and the price and weight are so low it makes it pretty much perfect.

Awesome low end

By 

from Rocklin, CA

Comments about Gallien-Krueger MB115 1x15 200W Ultralight Bass Combo Amp:

I've been using this amp since last august and I have to admit, this amp is awesome, and a great deal for the amount that I paid. However, I have found that the single 15" speaker does an amazing job on the low end (the entire house shakes at about half volume) but doesn't have hardly any power at all for the high-mid to treble, even when the tweeter is on. Great for bassists who stick to the E or A strings primarily, or somebody that plays every once in a while in a band. (plenty loud enough to be heard over the drums)

Great Amp

By 

from Michigan

Comments about Gallien-Krueger MB115 1x15 200W Ultralight Bass Combo Amp:

This amp is far from a practice amp, it's very loud, and the sound I get out of it is very clean and nice. I really enjoy using this amp! It beats Acoustic brand amplifiers, and being a digital amp I was impressed with it. Tube amps sound great, but digital amps like this sound fantastic! Gallien-Krueger did an amazing job with the MB115. I would recommend this amp to any serious musician.

Just Not Loud Enough.

Comments about Gallien-Krueger MB115 1x15 200W Ultralight Bass Combo Amp:

I ordered this for Rehearsal, but it wasn't loud enough. Great Sound quality, light weight, Well built Amp, but just not loud enough. Great for practicing by yourself, but not with a full band.

Awesome Amp with a Low price

By 

from Oak Lawn Illinois

Comments about Gallien-Krueger MB115 1x15 200W Ultralight Bass Combo Amp:

I bought this amp because i needed a bass amp. I was so impressed with it. I play Jazz, Metal, Rock, and Funk, and this amp does all of that. I've had this amp for seven months.I've pushed this amp to the edge of its functioning point and it still runs like a champ, using it for 6 hours on almost max volume and its not even warm. The bass in the Metal band i'm in Really needs to cut through, and this amp allows the sound to do that. People have pressured me to buy a bigger/better setup, i tell them that this is all i'm going to need for a while. This amp is extremely powerful and offers a variety of tones for the players needs, its also a very light amp and doesnt hurt my back carrying it around. If you want a great, powerful, lightweight amp for under $$$ bucks, this is the amp you want.

Very light, but powerful amp for the money.

By 

from durham, nc

Comments about Gallien-Krueger MB115 1x15 200W Ultralight Bass Combo Amp:

Having owned many different amps, I was looking forward to using the GK combo due to it's small size, it's wieght, GK's reliablity and sound. All of that being said, when I recieved it I was generally pleased with the sound, but I do feel it does not have that middle tone that I hoped it would have. Even with the horn it still comes across is basically a lot of bottom end, ultra high end, but no real middle tone. Working the eq helps a little, but having owned other amps I still find the mid tone lacking a bit. Still it's a great loud amp for the money and for most players I think it will do a nice job. Applications include practice, and small to medium size gigs.
