From Orange:

Created in conjunction with guitar prodigy and Grammy Award-nominated singer–songwriter Marcus King, the MK Ultra is our first-ever amplifier designed with Orange USA and built in the USA. Using the highest-quality components available, including American-made custom Heyboer transformers, this hand-wired 30-watt all-valve guitar amplifier represents a marriage of classic American and British tonal sensibilities. Make no mistake though, this is not a copy of a previous design with slight modifications. This is a unique innovation that offers a new approach to the trademark Orange sound.

The MK Ultra features carefully tuned input circuitry that not only responds amazingly well to different volumes and tone settings on your guitar but also takes pedals extremely well and moulds them into the tone instead of sitting them on top. This is driven by a pair of 12AX7 preamp valves feeding into a power amp section consisting of two 6L6GC power valves that are cathode-biased. This choice of output valves is a first for Orange, bringing out all the harmonics and touch sensitivity that Marcus demands.

Although this is a unique artist signature model (only 150 made), players from many different genres will be able to dial in their own tones and sounds. From country to blues, classic rock to jazz fusion, and everything in between, the range of this simple three-knob design has to be heard to be believed.
