Weighing in at fewer than 4 lb. and taking up less than one rackspace, the MB500 delivers 500W of signature GK tone in a sleek, compact, modern head. Boasting GK's legendary 4-band active EQ and contour control, the MB500 lets you tweak your tone to perfection before hitting the digital power section.
In addition to its generous tone-shaping capabilities, the preamp section has a footswitchable boost channel with independent volume control to dial in just the right amount of grind and level boost when needed.
The MB500 is stage- and studio-ready with an XLR direct out with pre-/post-EQ selector and ground lift. Also offers a tuner out with mute, FX loop, headphone/line out, and dual Speakon outputs.

After years of lugging around an SVT head, I found an amp that has the tone and volume needed to play anywhere from a small wine bar to any outdoor venue. This lightweight amp is easy to use, allows plenty of flexibility in tone and packs plenty of watts. Nothing beats a GK for quality at such a reasonable price. GK is not as flashy as some brands, but has been consistently excellent for many years.
Cant believe the size and weight of this amp! Add that with the power and all the features, and you'll love this head for a primary or back-up. I bought this so when I need to split my gear between home and rehearsal location, I have a great sounding, very portable head. Love it!
I wanted to be mad at GK for sending me an MB500 that was missing the limiter switch, but after having it serviced, I have decided to sell off my heavier gear. In fact, I just ordered an MB200 as a backup and for smaller gigs. I used to hustle a 40lb combo to my small gigs and a 100lb combo (PLUS A 50lb ext. cab) to my big gigs. Now, I just put my 3.5lb head in my instrument case and take either my 20lb Promethean 1x10 cab or my 75lb 2x15 cab. I have effectively cut both my rig's total weight in HALF without sacrificing tone and quality! Any gigging bassist HAS TO appreciate that! I was scared of digital circuitry for a few years. Not anymore. When I play gigs that provide backline, I still pack my MB500 because I'd rather use it than most of the heads provided. Plug it into a Ampeg 8x10 and it will PUNCH! Buy one, TODAY!!
I'v been using GK for 30yrs from the 200RB and then 800RB. In the 80's traveled all over with the 200RB and it fell off a pickup in San Antonio on the freeway, other than missing knobs and dents it got me though the gigs and never broke down (untill my wife chucked it out by mistake). The MB2-500 has been with me for almost 2yrs and it works week after week, gig after gig, worka great with my J & P basses, Ampeg Baby bass and Acoustic. Great amp for the money, flexability and great amp for the BACK!! If it's as reliable as the 200RB (so far it is)I'll get the MB200 for the smaller gigs.
I LOVE this amp. It is lightweight, really small and best of all it ROCKS. I know sometimes GK get some not so good reviews on some of their stuff but I really really love the sound of their amps. I play through 1x15 and 4x10 GK cabs - budget priced ones - but I get a fantastic sound with power to spare..... Couldn't be happier with this product. When the amp arrived, it had some scratches on it and I called to inform GC who were great about it and offered a replacement no questions asked. None of my local GC stores had stock and I did not want to have to wait for a replacement through the mail so I suggested them giving me a discount to keep the scratched one. Again - no questions asked they were happy to accomodate me....... HAPPY HAPPY HAPPY.....
I read the reviews. I ordered one and love it. Great tone and great tone control. You can really "shape" your sound. The foot-switch is a nice feature. You can kick it on for just a volume boost, or for the great GK crunch. I'm playing it through a GK 212 and love it. The size/weight is great too. I've only had it about 2 weeks and used it for 1 gig. So far works just as I want.
This amp is great for it's size,but it doesn't have the big bottom end and crisp highs as it's big brothers.I traded mine in for a GK 400 RB. Its light but has the big bottom and highs.Two-hundred dollars less. looking for small? OK go and get the MB500. Want small and muscle get the GK 400 RB.
This is a great little amp. I've used it on 5 gigs so far(2 weeks). It sounds clear and full and weighs 32 lbs less than my old rig. I am also impressed by how coolly it operates. A the end of the gig, it's just luke warm, and I play pretty hard and loud. Overall I would not hesitate to recommend this amp. It was out of stock when I placed my order, but within a day or two I received a shipped notice and had the amp (with free shipping) within a week of placing the order.
GK's version of this mini amp. Many mfrs. use the power amp, made by Bang and Olafson, and combine it with their own preamp, such as Eden, Gallien Krueger, Markbass, etc.. This is a good amp for the price, and very portable. Good for small gigs. One caveat: on earlier models, if left on for a long time, they tend to overheat and distort until turned off and on again. Newer units tend not to do this. In any case, there are local techs who can fix this problem under warranty. So if you like the tone delivered by GK preamps, considered this and a good 2X10 or 4X10 for small gigs.
Quite Possibly the best bass amp I have ever owned. I've played it with my P bass, Jazz bass, Peavey cirrus bass, and upright bass and there seems to be no limit to this little monster! It works sonically well with all my bass cabs from a 2x10, to 1x15, and 1x12. If your traveling or need to carry your amp and infant son. this amp does it all! Well worth the money and outdoes my Ampeg Portabass 800!
