@d_g is looking for one of these

Amazing sounding amp, but I'm going all in on my Darkglass Anagram, so it's silly having 4 amps laying around. Comes in a nice Gator rack bag, and with original footswitch. In very good condition and all working as it should. I'd rather not post due to the tubes, but would pack as securely as possible if you wanted to arrange a courier. Also happy to meet up within reasonable distance of High Wycombe, Bucks. The Fusion 550 incorporates a unique six stage tube preamp paired with the same high current analog power amp utilized in our RB Series. The rich warmth of tubes combined with the quick, punchy power section that GK bass amps are known for is an experience like no other. In addition, GK takes the next step in innovation by adding motorized controls which allow you to store two different settings that can be recalled via the provided footswitch It’s 500 watts @ 4 Ohms with a 50watt Biamp Pre amp three tube 12AX7. Class G Amplification: This type of amplifier uses multiple power supply rails, switching between them based on the signal level to improve efficiency compared to a Class AB amp, while still offering good sound quality. Tube Preamp: The Fusion 550's preamp section uses vacuum tubes (specifically three 12AX7s) to shape the initial audio signal, contributing to the amp's warm and tube-driven tone. Hybrid Design: The combination of a tube preamp and a solid-state power amp is a hybrid approach, often found in bass amplifiers, providing a blend of warmth and power.

Strange, I can suddenly only attach one picture!

This is a great sounding amp that has never let me down, and always got me compliments on my tone. In great condition except a small dent on the top that is hardly noticeable. Doesn't affect the operation of the amp on any way. Going all in on the Darkglass Anagram, so having 4 amps is very excessive! Happy to ship for cost, or meet up within reasonable distance of High Wycombe.

Sure is!

Great sounding preamp for Stingray style basses. Has a sweepable mids knob as well as bass and treble. Comes with control plate. There are really good fitting diagrams on the John East website, and John himself is always helpful if you need anything.

You should probably mention you're not based in the UK, it doesn't say on your profile in this listing. I got excited for a second!

If only it was in the UK 😢

Selling this as I had it on my second board, but recently got an Anagram and can do everything on one board. I used my other one of these for 5 years and never had a single issue. This one has only had maybe 20 hours of use. Price includes UK shipping.

I've still never tried a Trace amp... Everyone on here seems to love them. Seriously tempting. Are they good for classic rock / hair metal type stuff?

Haha, you don't know how long I was staring at this for yesterday, trying to figure out a way to make it work! I have my Barefaced 610 stack now, so have all my bases covered. Plus, I'd have to buy an Orange amp to go with it .. even more cash I don't have.

Hey, yes it is, I've added a pic now. Thanks.
