The product price includes a one year warranty and 30 day money back guarantee.

However, the Gear4music extended warranty scheme provides an enhanced service, and is designed to offer a higher level of protection than many 'free' warranties offered by some retailers and manufacturers.

The highlights of this enhanced warranty service are:

  • Warranty is extended to 5 years from the date of delivery.
  • Our Money Back guarantee is extended from 30 days to 90 days (terms apply after 30 days)
  • Collection and delivery costs are included for the first two years
  • Claim 50% cash back on the cost of the policy after 5 years if it has not been used!
  • Warranty is transferable if the item is re-sold
  • Loan or replacement equipment will be provided if the product isn't repaired within 30 days
  • If an item can not be repaired, a similar alternative product or cash discount (as defined in this policy) will be offered
  • The policy can be cancelled within 30 days, and at any time after that for a pro-rata discount

Please note that this extended warranty is currently only available on products sold within the EU or EEA, and is subject to the terms and conditions as detailed on the extended warranty certificate provided.

For customers in outlying areas of the country, the price of the Extended Warranty may be marginally higher, due to the potential for higher collection and redelivery transport costs.

This enhanced warranty is in addition to the standard Gear4music and manufacturer warranty policies, and the Gear4music terms and conditions of trade. No statement or condition of sale contained within these terms affects or restricts your statutory rights as defined under the Consumer Contracts Regulation 2014.

Gallien Krueger Fusion 550 Bass Guitar Amp Head


The Gallien Krueger Fusion 550 bass amplifier head incorporates a uniquely designed six-stage tube preamp paired with a 500 watt version of the high current solid state power used in the 1001RB-II bass amplifier. The rich warmth of tubes, combined with the quick, punchy power that Gallien Krueger bass amps are known for is an experience like no other.

And as if that wasn't enough, Gallien Krueger takes the next step in innovation by adding motorized knobs which allow you to store two different settings. This allows you to set a separate clean and overdrive tone, or a slap and finger style tone and foot switch between them. A first for a fully analog bass amplifier! Yeah tube amps have been around for decades, but you've never heard one like the Fusion 550.
