Orange MK Ultra Marcus King Signature 30 Watt Guitar Tube Amplifier Head

Orange Amplification has joined forces with Grammy Award-nominated guitarist Marcus King to create their first-ever American-designed and built amplifier, the MK Ultra. This exceptional 30-watt all-valve guitar amplifier combines the finest American components, including custom Heyboer transformers, with meticulous hand-wired construction that bridges classic American and British tonal characteristics.

The MK Ultra’s sophisticated input circuitry responds brilliantly to your guitar’s volume and tone adjustments while integrating pedals seamlessly into the overall sound rather than layering them on top. Two 12AX7 preamp valves drive a cathode-biased power section featuring a pair of 6L6GC power valves, creating a circuit that’s both urgent and responsive.

What sets this amplifier apart is its unique EQ design, with independent tone controls positioned strategically throughout the circuit. These controls were specifically voiced for Marcus King’s requirements, making it virtually impossible to achieve an undesirable tone. The Volume control functions as much as a tonal shaper as the dedicated Sing and Deep controls, thanks to the circuit’s dynamic interaction with your playing style. The cathode-biased design ensures fast response times even at lower volumes, making the MK Ultra an ideal foundation for any pedalboard setup.
