Overview

Continuing the evolution of the MB Series, the MB800 bass amp head from Gallien-Kreuger features incredible output, increased functionality, and a completely discreet FET-driven preamp. With 800 massive "GK watts" of power, the MB800 can handle even the largest venues without breaking a sweat, and at 5 lb., neither will your roadie!

All of the MB800's controls are lit to indicate the current operating status, including input clip, tuning mute, Gain A, Gain B/Level-B, power amp clipping, limiter enable, and EQ/Contour settings. The same FET technology used to create the legendary boost (G.I.V.E.) circuit found in all GK amplifiers for over 30 years is used in every stage of the MB800 preamp. Using FET devices to drive the GK four-band active EQ, Contour, and Gain allows the MB800 to transition seamlessly from a full, warm, clean tone to full-on GK growl.

FEATURES

  • 800W @ 4 ohms, 500W @ 8 ohms
  • Discreet FET preamp
  • Push-activated Gain A/B and limiter defeat
  • -10dB pad
  • 4-band active EQ with variable contour
  • Effects loop and tuner mute
  • XLR out, pre/post EQ

  • Two Speakon outputs
  • Headphone/line output
SPECIFICATIONS

After only playing 3 hours

By Heath McLaughlin

from Texas

Comments about Gallien-Krueger MB800 800W Ultralight Bass Amp Head:

Features: As I admitted I have only had a few hours of playing around with this thing but I am impressed. It is not hard to dial in any tone I am looking for, the EQ is easy to use, and it has 2 channels that are footswitch controlled allowing you some additional control. Footswitch and cable come with the head, do NOT have to buy separately. Quality & Reliability: This is a new product and I have not had it long enough to know how reliable it is going to be over the long hall. The shell seems like it will hold up though. Only time will tell. Also you can't go wrong with GK costumer support/service. Sound: This is a full 800 watt amp head. I have played on some "high watt" amp heads that didn't produce the sound, tone, or volume I was expecting. This is not the case with this amp head. As I mentioned before I was able to get an array of tones out of the head. And if volume is something you are looking for, this head will for sure give you plenty of it. Matched with the right cabs I would see no reason for you needing a "bigger" or "louder" head. Look & Feel: This is what makes this amp different from the others on the market. It is light and easy to carry. Very low profile. The illuminated dials make it easy to read, and look cool in low light :). First gig with it is in a week. Ready to stretch its legs.

    Comments about Gallien-Krueger MB800 800W Ultralight Bass Amp Head:

    I have been playing bass for almost 40 years. Lately I have been looking at smaller more portable amps for traveling purposes. I bought this about 3 months ago and was immediately impressed with the powerful sound. The sound quality is at least as good as any other amp I've used, and I've used quite a few. Paired with the GK Neo 4x12 cab, I easily fill any space I play, large or small.
    I play in 4 different bands with different genres. This amp can handle all 4 genres easily, with two channels and easy to use controls, I can change my sound easily. It blows away the ampeg pf800, which I sold as soon as I heard this one.

      Comments about Gallien-Krueger MB800 800W Ultralight Bass Amp Head:

      I wanted a small, lightweight, powerful amp to be used as my main amp. I got it with this MB800. Paired up with a G-K 2-12 Neo cab, I have a rig that will work just about anywhere we play. You can dial in any sound you want and there is plenty of punch. I remember hauling around two Marshall stacks and then two SVT rigs back in the day, but, all things considered, this is much better. Total weight of my bass rig is about 50 pounds now and if I need more volume, I let the PA take care of it. Great set-up.

        Comments about Gallien-Krueger MB800 800W Ultralight Bass Amp Head:

        This is the best value and sound of any bass amp I have ever played with. I have been playing bass since 1963. Driving one 8ohm JBL 15" cab. And one 8ohm Bergantino 210. Best sound i ever had. Limitless headroom. Outside inside whatever the venue. Very Happy.

        PS use GK MB 200. as back up. never had to use it except for small gigs.
