Description

The Fusion 500s combines the warmth, dynamic and harmonic complexity of a valve preamp with the superior power capabilities of a solid state power amp, so you can get that authentic valve tone without sacrificing power or volume. With a trio of  12AX7 preamp valves there's more than enough tone-shaping ability and gain to achieve any tone you're looking for. The 500s has the versatility of 2 channels – clean and overdrive. For additional control, it contains "bump", "contour" and "presence" switches and an effects loop.

Having 500W of power at your disposal can be great in certain situations but it's not always necessary. Gallien-Krueger have remedied this by catering for a myriad of different applications, with a balanced DI for recording straight to desk either Pre or Post EQ. It also has AUX and headphone inputs, ideal for home practice, and a variety of load options to pair to almost any cab. So whether you're gigging, recording or just playing at home, the 500s with truly do it all!

Here's what Gallien-Krueger say about the Fusion 500s Bass Head

The Fusion S Series Heads are GK’s brand new Class D Model heads with a tube preamp. 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. These high powered heads incorporate three 12AX7 tubes in the preamp, including one dedicated to the overdrive channel, making it GK’s first ever tube driven overdrive channel. Illuminated knobs add an extra level of sophistication and design by not only making it easier to dial in your tone on stage and but adding a beautiful stage presence as well. Each illuminated knob is also push activated, with additional voicing filters and tonal characteristics built in. Like the Legacy Series, the Fusion S series uses a unique interconnection system that eliminates problems that can develop over time from constant vibration and temperature extremes that gear is subjected to with heavy use. Using circuit boards with gold plated connectors, rather than cables with standard tin connectors, this type of construction delivers a more pure, reliable sound. Features include GK's classic 4 band EQ, tube Overdrive complete with tone shaping, additional push button voicing filters such as "Bump", "Contour", and "Presence", Balanced DI with Pre and Post EQ, an Effects Loop, Aux and Headphone connections, and Load capacity selection, to deliver optimum power into 2, 2.7, 4 and 8ohm cabinet configurations.

Amp

An amp is an amplifier used to boost the signal from a guitar and shape its overall tone and volume. It plays a major role in how a guitar sounds, influencing everything from clean clarity to natural overdrive and distortion, and is a core part of any guitar setup for both practice and live performance.

Amp Head

Guitar amp heads contain the main tone-shaping and power section of an amplifier, designed to be paired with a separate speaker cabinet. They let you choose different cabinets to suit your sound and setup, offering flexibility for home, studio or live use. If you want control over volume, tone and character without being tied to a single combo format, amp heads give you a modular way to build the rig that works best for you.
