    The little amp with a big sound

    Forget those other entry-level amps if you want your bass instrument to sound like a bass instrument. This one can do everything from emulate that old 1970s Vox tube-type warm depth to slapping and popping with the best modern players. And it will easily do so in a 3- or 4-piece group in a medium-sized club, church -- whatever. I wanted the 15-inch speaker to go with the deep sounds of my Kala U-Bass 5-string solid body (that we also got from Sweetwater) and man does this one ever come straight up out of the caves. Just because it's low-end for G-K, doesn't make it low end for the musical field. This MB115 is serious equipment. Spend more and go bigger if you need that, but if small cabinet and big versitility is your deal, get one of these bad boys today.

    Gallien Krueger MB115 is Awesome!

    I have a few big rigs with 2-15"speaker cabs.I also have a bad back. So I was looking for an affordable,light weight combo amp to replace the very heavy Mesa Boogie Walkabout amp I was borrowing and lugging to gigs. My band plays charities and fund raises, usually at some country club, or poolside at some donor's private party.I have tried the Mark Bass,the Promethean, The Shuttle, and all the small but powerful light weights available.But for my needs and the price. This amp rocks with room to spare over 2 guitars,Bass,keys,drums and 5 vocalists

    Great value, great sound in a small package

    The amp delivers plenty of deep bass tone. It can get loud if you give it a push.

    It's a pleasure hauling it - very light. I'm very happy with the amp.

    Gallien Krueger MB115

    TMB115 was just the amp I was looking for. Big sound when you need it an good tone to go with it. It's also light, which is another plus. In addition, dealing with Sweetwater is simple and they follow-up to ensure your satisifaction.

    Great Amp!

    This amp is amaizngly lightweight. It is very easy to get in and out of anywhere needed. I bought this amp for small gigs so I didn't have to lug around my ampeg svt3pro and 410hlf (well over 100 lbs of gear). The MB115 sounds much better than i expected for $400. The EQ is easy to use and the 4 bands give great control over the sound. The loudness just barely cuts with with a loud drummer. It is adequate, but with no extra headroom. I would recommend this amp for small bars/gigs with no PA support or medium sized gigs with PA support. I have read other reviews that state the direct out xlr jack is poorly designed. They are correct, and xlr will go into the jack fine, but the button is right against a lip and you need a pocket knife to get the cable out. (the reason for 4.5 stars) Other than that, it's great!

    Super Amp!!

    This amp produces the bottom and tone I've been looking for since I used an 18-inch Kustom in the 70s. It has HUGE bottom end and the crispest highs I have ever seen in a bass amplifier. I've used several models of Fender, Peavey, Kustom, and Crate, but the GK MB115 is the only one that completely satisfies what I want with its tonal variations. It's also super lightweight and very well constructed. My only suggestion is that GK build in a tuner and turn the XLR output around. Super amp!!

    I ordered this amp and it was delivered upside-down in the GK box, the phones jack was unscrewed and in the bottom of the box, and the speaker was blown. I give GK a 1 star for this. However, Sweetwater replaced it immediately with pre-paid shipping and with great customer service. I give them a 5 star for sure. The new amp came and is working great! Thanks SW!

    My first GK amp and I'm happy!

    I plugged it in as soon as I got home and I had to remember the neighbors! I will be using it for weekend gigs....My drummer likes sitting with his back to the bass amp, so he should enjoy this! No complaints yet...I think I made a good investment for half the price of other combo amps like this? This is my first Gallien Krueger and I am impressed!

    Great Amp for the $$$

    This amp has a great tone and a lot of volume. I play it with my MM Stingray 30th ann. The tone that comes out of the amp is wonderful as well as the volume. Every note comes out clean with no hesitation. The 2 problems I have with the amp is the direct out and no switch for post/pre eq. The direct out jack is facing the cabinet. When you plug in an XLR to get it out you need to use your keys or a pen to pry the locking switch. Also the direct out signal is pre-eq which kind of sucks. Otherwise great amp!

    Not Happy

    Mine died after 3 years of very light use. I'll stay away from GK in the future.
