The Gallien-Krueger Fusion 550 is GK's first bass amp head featuring an all-tube preamp. The Fusion 550 bass head incorporates a uniquely designed 6-stage tube preamp paired with a 500W version of the high-current solid-state power amp used in the GK 1001RB-II. The rich warmth of tubes, combined with the quick, punchy power that G-K bass amps are known for, is an aural experience you must hear to believe.

As if that wasn't enough, GK has inventively incorporated motorized knobs into the Fusion 550 head that allow you to store two different settings. This gives you the ability to dial in a separate overdrive or slap tone and footswitch between them-a first for a fully analog bass amplifier.

The Fusion 550 amp also features a simplified version of GK's exclusive 50-W Horn Bi-Amp System. Dial in the horn where you like it, and as you adjust your volume with the master control, the ratio between the woofer and tweeter is preserved. Other features include a tube driven 4-band active EQ and voicing filters with a frequency select for the contour control. The rear panel features include Neutrik Speakon and 1/4" speaker output jacks, effects loop, tuner out, and a footswitch input jack. It also has a DI output which uses an isolated transformer for ultra-quiet operation.

Hands down one of the finest bass heads I've ever used! I still own my first Gallien Krueger 800 RB head, and it has never let me down! The new Fusion uses the same 4 band tone shaping as the 800, but took the preamp section to the next level. Dual, foot switchable channels, motorized controls, and tons of power make for an instant classic! You must try this head!

Great head, have it paired with a Neo 410/4. The tubes give it a nice warmth, a/b'd it against a few other heads including the GK MB Fusion and this one was the clear winner. Only downside is the price, should be a few hundred bucks less.

Once you've used this head, nothing else compares. The clear, punchy tones and warmth of the pre-amp make everything else seem inadequate. I've tried using other combos, heads, but the GK Fusion 550 has set the new standard for me. Not a single bad thing to say about it.

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.
