    I've always owned two bass heads so I'd have a backup.

    Recently, I acquired a somewhat capable combo, so felt it was time to ditch the spare head.

    This plan was a dumb idea, since hauling around a large combo with my rig, was not practical. I needed something small; like a doughnut spare that most cars have. It didn't have to be as capable as my main bass head, but had to be just enough to get me through any gig.

    Enter the GK MB200

    PROS:
    -This amp is tiny, light, and will fit into the pocket of most gig bags.

    -The tone is what floored me. It has an aggressive, punchy, tight sound that makes my main head seem ho hum.

    -I'm in a KISS tribute band. This little amp got me easily through a gig when my main amp started having issues. It had plenty of juice, nicely powered one of my cabs, and I occasionally use it at rehearsals now.

    -The EQ is simple, and easy to dial in on the fly.

    -The price is right for a quality piece of gear.

    -The fan is quiet.

    CONS:
    -Speakon is the only speaker output on this amp. My main amp has banana jack and ¼".

    -My main amp has an efx loop that I use with my rack tuner for muted tuning. This amp just has line out and a return, but the return is 1/8" jack.

    -The power cord that it came with didn't securely seat into the amp's electrical socket. I swapped out the cord, and no further issues.

    -If you're one of those who likes parametric EQ's, this amp may be too simple for your taste.

    -It can really only power one of my 410 cabs. My main amp can power both.

    -The biggest advantage and disadvantage this amp has is its size. While small, light, and easy to transport, it can also be easily stolen at a gig. However, if rack ears are purchased, it can be racked. A nice idea, but placing this amp in a bulky rack defeats the purpose of owning a micro head.

    I'm happy with my new spare amp. It gives me exactly what I need, and it is way more powerful than I anticipated. I am so impressed that I plan swapping out my main amp with the MB200's 800 watt big brother.

    In that I was ultimately dissatisfied to the degree that I decided not to keep the amp, again, I have to personally give it a "Terrible" rating. Again, setting aside the noise level issue I experienced, I took it a rehearsal and small bar gig, and it did well. I play classic rock next to a loud drummer, and in that situation, the MB200 was capable a produced a great sound. In terms of wanting to carry it as a back-up and use it at home for practice, I could not accept the noise level.
    The feature set on this amp is nice, but expectedly and appropriately limited, considering its size and price class. The lack of a master volume or mute feels overly limiting in certain situations. The basic set of tone controls can be looked at as refreshing and offers a great range of usable sounds. The contour switch brings you immediately to a nice, fat, rich bedroom tone. Not so great in a band situation but a great sound for practice. A really nice feature is that the line-in goes through the speaker output, giving you the option to do heaphone or speaker practice. Other amps that I'm aware of limit line-in to headphone out.
    I believe the overall quality of construction of this amp is decent, but I give it a "Terrible" rating due to the hiss noise level I experienced. I noticed a significant hiss noise was always present, whether cabinet or headphone, even with the gain at 0. I exchanged the first one I got and found the same problem with the second unit. I have returned the second one for refund.
    Setting aside the noise problem, this is a great price.

        Great little amp. I was surprised at the tone and quality. Extremely portable. I ran it through an Ampeg 4x10 HLF cabinet using a Warwick Thumb N/T. The sound was impressive.

            Comments about Gallien-Krueger MB200 200W Ultra Light Bass Amp Head:

            I own an Ampeg Classic tube amp and go through the Ampeg 810 fridge or a 410 HLF. Like many others who discovered the GK MB series, I was looking for alternatives to the cumbersome amps and cabinets. I decided since I was "experimenting" with the Class "D" amps I would start with the least expensive GK amp. For over 30 years I've only played Ampeg or GK. I also purchases a GK NEO 1x15. Sorry to say my Ampeg set-up is no longer needed. Not to say I wouldn't use it in a stadium, but with the purchase of one more GK Neo 1x15 daisy chained, I get all the punch I'll ever need out of this flyweight MMA fighter. I appreciate the Spartan useable controls as well as the fact that they actually make a desired difference when used. Too many amps out there have 11 knobs and one tone. A flip of the contour to *on* and I get great slap tones, flip it off and there's the GK midrange growl I love without changing the tone controls. I circumvented the issue of it vibrating off by looping a large (rubber band?) through the handle of the cabinet and around the amp. I actually get butterflies again when I'm gigging and get to use this set-up. With the two Neo 1x15's it changes to the 4 ohm power and sounds absolutely amazing. BTW this is the first time I've ever used 15's, and I see why they have always had a place, but that's another review. Thank you Gallien Krueger!!

                This is a great amp for a backup or for practice. The controls are limited -- no master volume (just gain), no compression, but it does have the basic EQ. The tone is good. If you connect it to two cabinets (or, I assume, something like a 4-ohm 4x10) it can get plenty loud. It is perfect to take a long as a backup in case your main amp falters. Also, anyone considering a small to medium sized combo amp for gigs should consider this head. It will give you options by pairing it with different cabinets. Apparently some of them have had noise issues but mine is totally quiet.

                  Got this to reluctantly replace my old GK 400RB which has been my backup amp for years and is great for small venues and practice. The much lighter MB200 also has headphone out and an auxiliary input which came in handy to plug in my sansamp bass driver directly and bypass all the tone and volume controls. Great feature! This gave great output. I found the GK tone controls a little boomy by themselves, but use my Sansamp most of the time anyway so bypassing all the volume and tone and using this like a micro slave amp was a huge plus. I push it through my practice cabinet too which is an Eden EX112. Great punchy tone!

                  Purchased the MB200 to pair with an Ampeg SVT210AV cab that I already owned and it sounds fantastic! This pairing has made for a lightweight, compact rig that I will use for small venues where space and volume is an issue. Plenty of low end, with a nice clear, defined bass sound. This setup would not be loud enough to back a rock band at full volume, but I am incredibly happy with it for what I will use it for, backing a folk/country rock style band with a drummer who plays at moderate volumes.

                    So, let's get this out of the way. The description above is wrong. This is not a digital power amp. It is a misnomer that Class D stands for Digital. "D" is nothing more than the letter that follows "C" in the alphabet and does not denote "digital". Class D is analogue just like traditional A/B amps. A SMPS acts in an on/off, "switch" like manner, but this is still an analogue power amp. Your signal is not converted to a digital bit stream.

                    I've had this amp for a couple of years now. Mine had the high pitched hum issue, but after a round trip to Cali to visit GK it is now perfectly silent. In fact, this is the quietest amp I've ever owned.

                    The MB200 has a lot of power for a tiny, 2 pound, 200 watt micro. It drives my cabs hard and sounds great too. Given sufficient cabbage this head will get you surprisingly loud.

                    The tone is very Gallien-Krueger. Good, warm tone with a little grit and a scooped, bass heavy GK eq. It doesn't take much knob twirling to get a good tone out of this head.

                    Other cool features include the CD/MP3 input and the ability to use the amp with no cab, just headphones. This makes the MB200 a great practice tool that can fit in the pocket of your gig bag.

                      First off,I'm not a bass player.i'm a pedal steel guitarist since 1975.In my playing career,i've owned amps that were and still are "Standard of the industry"for steel guitar pickers.They often come in a large & heavy package.I came across some posts on the Steel Guitar Forum with high praise for this amp & decided to try one.A lot of us older players(I'm 60)just don't want to carry all that weight anymore,esp.if you play a not so lightweight steel or double on guitar & are carrying a guitar amp as well.(i take along a Fender Deluxe for my Tele)I'm running this amp with a 112 cabinet & a reverb pedal.This is the best pedal steel tone i believe i've ever had!Bottom end is deep but punchy with low notes well defined,mids are excellent,no "honkieness",highs are sweet and clear without being piercing.Overall,through the whole range of notes on my Rains SD-10,i get exactly what i'm looking for or should i say,listening for.Bass players,if you're using the MB-200 & play in a band with a steel player that's "fighting" their amp for the tone they want,please,turn them on to this!Just a note here,if you are looking for a way to safely transport your MB,the Musician's Gear Hardshell Harmonica case @$44.99 is a worthwhile investment.I already had one & discovered that it fits the MB as if it were designed for the amp.It fits snugly with room where the removable harp trays go to store the power cord,instrument/speaker cables & my reverb pedal comfortably!Thanks G-K and Musician's Friend for great products & excellent customer service !!!Bob Poole/Johnny Owens & The Rounders

                      Comments about Gallien-Krueger MB200 200W Ultra Light Bass Amp Head:

                      I am a guitar player who dabbles with the bass, and wanted an inexpensive, but good-sounding amplifier. This amp does the trick. The only bummer is the Speakon output, you need a $12 adapter to use a 1/4" cable.
