800W Ultra Light Bass Head w/Tubes

SKU: # 379592   |   Model: # MB-FUSION800   |    Product Reviews4 Reviews  Write a Review

Gallien-Krueger has expanded its MB series bass amplifiers with the MB Fusion 800, an 800-watt amp that brings together an all tube preamp and a digital power amp. Similar to the rest of the line, the MB Fusion 800 is built with an aluminum chassis and is sized to fit in a gig bag for easy portability.

The MB Fusion offers many of the same features as the regular MB Fusion, including dual gain stages, a contour filter, and a 4-band EQ. The contour filter and mid-frequency controls are selectable by pushing the knob and setting the frequency you want to adjust. Pushing the Master Knob engages or disengages the built-in limiter, and pushing the Gain A and Gain B knobs allows you to drive the tubes to get different tones in tandem with the Level-B knob. All of the controls are backlit and change colors when engaged including the mute switch to make your settings clearly visible.

Back-mounted features include a selectable headphone/chain/line output, and XLR out with pre/post EQ switch, a footswitch jack and an effects loop.

Lots of possibilities for a variety of tones. Perfect shape, size and weight for anything related to a musicians lifestyle. Little pricey. However the three 12AX7's as a built in preamp really pays off. I pair the MB Fusion 800B with an Ampeg HLF410. It sounds FANTASTIC.

Yes it is a bit pricey but its totally worth it. GK typically understates their claimed power and this amp is no exception. This amp will eat most if not all 800 watt amps for breakfast, it is loud and powerful. The gain channel (B) is a little less GK sounding, its not as clear as channel A (which sounds like a MB800). This makes the amp more versatile. If you are looking for punchy powerful tone with mucho power this is the amp for you.

I was looking to replace my GK 1001RB with something similar. I had been using a tube preamp with it and loved the tone I was getting. With the MB Fusion I was able to get both a tube pre and a powerful amp in one package.. and it's tiny. The choice of solid state or tube preamp really adds a ton of tonal versatility to this unit. The output power is massive. It's incredibly deceiving that this little unit can push so much air, and not lose any tone while doing it. Very clean output at all levels. I'm very impressed. I run it through Mesa Powerhouse cabs. 2x10 and a 2x12.

I bought this head after having the Fusion 500. I just wanted more power and this thing delivered as expected. It's got that GK tone, but it has more "depth" than the solid states. Light weight, light up controls are the only thing "light" about it. Looks are deceiving, she packs a punch.

Performance Warranty Banner

Protect your investment with the Long & McQuade Performance Warranty

A warranty can be a very important factor when making a buying decision. Because repairs can be very expensive in terms of parts and labour costs, manufacturers usually only provide one year limited warranties that generally only cover items that malfunction due to a manufacturer’s defect. With an important purchase such as a musical
instrument or piece of studio gear, however, many people want to have the peace of mind in knowing that their investment will be protected should the product no longer be performing at 100%.

Because of this, Long & McQuade provides our customers with a FREE one-year Performance Warranty on most of our products. The Long & McQuade Performance Warranty supplements the manufacturer’s warranty to ensure that our customers receive complete “no hassle” warranty coverage within their first year.

How does the Long & McQuade Performance Warranty differ from most manufacturers' warranties?
  • Performance Guarantee: Normal wear and tear is covered, so your product will be performing as well as the day you purchased it for the entire duration of the coverage. Band and Orchestral Performance Warranty does not include replacing pads or cleaning for woodwind instruments, unless deemed necessary by our repair staff. Ultrasonic cleaning for brass instruments will be provided if deemed necessary by our repair staff, but is not routinely offered under the Performance Warranty.
  • Product Replacement: If your product cannot be fixed or costs too much to fix, we will replace it with the equivalent model for no additional charge. If this is not possible, a full refund will be provided.
  • No Lemon Policy: Your product will be replaced should the same problem occur multiple times.
  • Convenient: Easy drop off and pick up of the product at any Long & McQuade location.
  • Guitar Setup: Guitars purchased at Long & McQuade come with 1 free setup, to be redeemed within 1 year for new guitars and 90 days for used guitars.
  • Loaners Available: A loaner product may be given while the product is being repaired.
  • Power Surge Protection: Your product is covered even if damaged from a power surge.
  • Accessory Coverage: Any peripheral devices or accessories that come with your product (i.e. foot pedal, case) are also covered.
  • Commercial Use Coverage: Music and recording professionals who purchase gear for “heavy-use” commercial purposes will still be covered.
 

Long & McQuade reserves the right to restrict the purchase of additional years of Performance Warranty. Used products come with a 3-month Long & McQuade Performance Warranty. Some products (i.e. computers, software, cymbals and other items) are covered only by the manufacturer‘s warranty. Consumables (i.e. strings, reeds, drum sticks, batteries, tubes, cross faders) are excluded as they are designed to be replaced. Cosmetic Damage, Accidental Damage, or problems caused by Humidity or Temperature Issues are not covered. Speakers damaged by overpowering are generally not covered. Our coverage does not provide compensation for loss of use. As of June 2018 the Performance Warranty is no longer transferable. The warranty is only valid in Canada.

Purchasing additional years of coverage

Some manufacturers provide warranties for longer than 1 year; however, these are usually limited warranties that do not provide the same coverage as the Long & McQuade Performance Warranty. Customers interested in more complete and convenient (but not necessarily longer) coverage are still able to purchase additional years of the Performance Warranty.

If you are interested in receiving this coverage for longer than one year, you have the option of purchasing additional years of the Performance Warranty. The pricing is as follows:

  • NEW products: 4% of the current new selling price to double the warranty from 1 year to 2 years. 4% for each additional year.
  • USED products: 4% of the current new selling price to increase the warranty from 3 months to 1 year. 4% for each additional year.
  • GUITARS: 4% of the current new selling price to double the warranty from 1 year to 2 years. 4% for each additional year. $45 maximum. An additional free setup is not included with additional purchased years of Performance Warranty.
  • BAND and ORCHESTRAL instruments: 4% of the current new selling price to double the warranty from 1 year to 2 years. 4% for each additional year.
