Orange MK Ultra Marcus King LTD 30W Head

Signature hand-wired 30-watt guitar head with a touch-sensitive, versatile tone and a beautifully simple 3-knob design.

US and UK Fusion

For the first time in their illustrious history, legendary company Orange crossed the pond to bring an amplifier to life. The MK Ultra guitar amp head was completely designed and built over in the States, resulting in an inspiring tone that fuses vintage British and American flavours. This signature amp was designed in close collaboration with renowned guitarist Marcus King and offers a fresh take on the iconic Orange sound thanks to its unique handwired design. Only the best quality components have been used throughout the MK Ultra, including custom American-made Heyboer transformers.

Tuned Input Circuit

Aside from its distinctive sound, what Orange’s MK Ultra apart from the pack is its straightforward 3-knob layout, independent EQ sections and meticulously tuned input circuitry. Players who prefer to go straight into the amp will love the way the MK Ultra dynamically responds to your touch and the settings on your guitar. By varying your attack, manipulating the volume control and tweaking the tone, you can go from warm, articulate cleans to singing, saturated drive in an instant. If you’re running a plethora of pedals, you’ll be pleased to know that the Orange MK Ultra is also a fantastic pedal platform that seamlessly moulds your effects into your tone.

Dynamic Tone

Driving the Orange MK Ultra signature guitar head is a combination of two 12AX7 preamp valves and a pair of cathode-biased 6L6GC power valves. The MK Ultra is the first Orange amp to feature 6L6GC output valves, which deliver the rich harmonics and dynamic touch sensitivity that are an essential part of Marcus King’s sound. Whilst this amp’s artist is praised for his incendiary Southern Rock and Blues style, the MK Ultra can handle practically any genre. Aggressive Rock, elegant Jazz Fusion, crisp Country and more - all of it can be effortlessly dialled in with the MK Ultra’s streamlined 3-knob layout. You definitely don’t need to be a Marcus King fan to appreciate the jaw-dropping tone and versatility of the MK Ultra.

Huge Sweet Spot

Tone-shaping is handled by the Sing and Deep circuits, which are totally independent of each other. Tweaking the Sing knob doesn’t affect what the Deep circuit is doing and vice versa. The ranges and frequencies of the MK Ultra’s EQ controls have been specially voiced to Marcus King’s specifications, presenting a massive sweet spot that’s easy to dial in.

Independent EQ Controls

Whilst Sing can be thought of as the “Treble” control, it’s more of a variable input bright control. By adjusting the Sing knob, you can perfectly match the MK Ultra to your favoured guitar and the venue you’re playing in. Deep offers something different than a traditional “Bass” knob and thickens out your tone. Once you’ve set up the Volume and Sing knobs how you want, you can gradually turn up the Deep knob to add as much thickness as you want.

Astounding Overdrive

The MK Ultra’s Volume control affects the tone as much as the others. Players with pedalboards will appreciate the seriously fast response at lower settings. Cranking up the Volume introduces delicious saturation with a slightly spongy attack that’s inspiring to play with. Even with the Volume control dimed, you can tame the MK Ultra’s ferocious overdrive by simply rolling back your guitar’s volume knob.

If you’re looking for a premium guitar amp head with a dynamic, highly-responsive tone that’s incredibly easy to dial in, you need to plug into the Orange MK Ultra.
