Wow!

I was looking for a small lightweight bass amp that would cover small to medium sized rooms. My salesman Bob Furlong had mentioned this amp and I am so glad that he did! I played my first gig with it and Wow! It has a great tone for bass and it has no problem staying up with a full band all by itself. If you find yourself needing more headroom, Gallien Krueger has self powered cabs you can add to give you what you will need. What an amazing concept!

Gallien-Krueger MB112-II 1x12

Awesome Amp... GREAT sound produced with my Ibanez AGB200 Bass; super lightweight; portable with great balance carrying; CD and Headphone connections are very nice; equalizer. Friends and family have complemented the look and sound! Sweetwater pricing, sales and tech support is the best I've found locally or on the Web.

Best Bass Amp that ANY MONEY could ever buy!

I don't normally write reviews but I felt I had to on this one. Geoff Allen, my sales guy, really recommended this amp so I took a gamble on it. To be honest, I'm really more of a guitarist who plays bass for needy gigging musicians. Also, one very important point, I've owned 19 basses and have never actually owned a BASS amp...mainly because most of my bands already had an amp for me and on some, I ran directly into the PA. When the box arrived, I was thinking-"man this might be heavy," but after carrying it to the bedroom, I felt different. It's light and LOUD. Very LOUD and the EQ system is just wonderful with many options of tone. Especially if you own a bass that doesn't have much tone. I have a Geoff Gould Modulus in surf green(EMGX Pickup). It has a lot punch. The thing I noticed the most is when you turn up the volume, it doesn't distort or loose tone. Having the controls in the back of the amp is a nice feature especially with headphones. BUY IT...You'll thank me later!

Hear the Punch! Feel the Thump! All In 3-Dimensions!

I'm been playing keyboards and left hand key bass for more than forty-eight years. For the last eleven years I've used the Yamaha S90ES Synthesizer playing right hand piano, electric piano, brass and organ sounds into the PA while using my left hand to play a finger style bass patch through an assignable dedicated output routed into a Polytone Mini Brute III 15" 140 watt combo amp. I thought that I had a pretty good sound overall. Last Saturday night I got to debut my new Gallien-Krueger MB112-II on a house gig which my trio has played for over eight years. The crowd there loves us and is very familiar with our sound. I expected this GK to be an upgrade to my sound but I didn't realize that it would be such a dramatic improvement. My drummer and guitar player were suitably impressed but our fans and regular customers all noticed the difference too. I've got a real bass sound now with Depth, Punch and Girth. When I hit the keys harder, my bass tone responds with more bite like never before. The crowd danced more than ever. I even had two girls in their twenties ask if they could come on stage and dance behind me while I played my keyboard rig. I'm sixty-six by the way so, I said yes but please be careful. I never realized what I was missing. Yes, I was playing the right notes and emulating the feel of a bass player pretty well but, I've never had this much fun doing it and I've never felt the fundamentals and foundation coming out of my amp which the rest of the band's sound is built on. It doesn't make any sense that such a big sound can be coming out of such a small and light package. There is definitely some magic fairy dust going on in the EQ and Porting on this cabinet. I was sure that I would try out the MB112-II, be very pleased but then arrange to return it and swap it out for the MB115-II. I'd read in various bass player forums that the MB112-II is really loud. I didn't believe them but, they were right. It is really loud but, in all of the good ways and none of the bad. Here are the settings that I was really happy with throughout the whole gig: -10dB Pad On - Contour On - Gain 12:30 Treble 1:00 Hi-Mid 1:00 Low-Mid 11:00 Bass 11:00 Special Thanks goes out to my Sales Engineer Ed Nystrom - You were right yet again!!!

Great Product

I've owned bass amps that were larger, more expensive and more popular brands, BUT NOTHING can compare with this amp. The sound, quality of the product and every thing about this amp is far ahead of any other. I am 110% pleased with The Gallien-Krueger MB112-II and Sweetwater is the way to go.

I've been really impressed by the sound quality and power of the Gallien-Krueger MB1120-II. This little 1x12 combo not only makes a great practice and rehearsal amp because of its size and light weight, but when I need more power for bigger shows I just daisy chain some GK powered cabinets for the ultimate modular bass rig!
