Orange Marcus King MK Ultra Head

The MK Ultra Head: The First Handwired Orange Signature Head from the USA

The Orange Marcus King MK Ultra Head is no ordinary signature amplifier. Designed in close collaboration with young American blues guitarist and Grammy-nominated singer-songwriter Marcus King, this is the first Orange amplifier to be entirely handwired in the United States. That's not just a statement, it's audible: the MK Ultra has an organic, breathable character that you rarely encounter in other amplifiers in this class.

The front panel has been deliberately kept simple: a Treble (Sing), Bass (Deep), and Volume knob. But anyone who thinks simplicity means limited is wrong. The three controls are exceptionally interactive and subtly responsive to each other, allowing you to achieve large tonal differences with small adjustments. From warm, soulful blues to cutting rock lines and fluid fusion tones: the MK Ultra effortlessly moves between styles, without ever losing its character.

The heart of the amplifier consists of a pair of 12AX7 preamp tubes and 6L6GC power tubes, a combination known for its warmth, dynamics, and expressive response. The 6L6GC tubes give the MK Ultra a typical American sound: full in the low mids, clear in the high strings, and with a breakup that remains musical to the extreme. Handwired, with attention to detail and built to last a lifetime.

For the guitarist looking for an amplifier with its own voice and a story, the Orange MK Ultra Head is an extraordinary choice.
