MK ULTRA – THE MARCUS KING SIGNATURE AMP
Created in conjunction with guitar phenomenon and Grammy Award nominated singer/songwriter Marcus King, the MK Ultra is our first-ever Amplifier designed 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 vintage American and British tonal sensibilities. Make no mistake though, this is not a copy of any previous vintage design with some slight modifications. This is a completely unique design that offers a new approach to the classic Orange sound.
The MK Ultra features very 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 together into the tone instead of sitting on top. This is driven by a pair of 12AX7 preamp valves into a power amp section consisting of a duet of 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.
While this is a truly unique artist signature model, 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 3-knob design has to be heard to be believed.
The VOLUME control
This is really as big as a tone control as the other controls. With the MK Ultra being a cathode biased amp it is urgent with a fast response time at low volume settings, making it a perfect partner for your pedal board. As you increase the volume control you will hear more saturation with the 6L6’s starting to break up giving you an almost spongy attack that will sing and make you want to play more and more. Even at full volume you still have clear control via your guitar volume knob.
The SING (Treble) control
This can also be described as a variation input bright control, bringing you the tone you need for the atmosphere you are playing in. Adjusting the sound to pair perfectly with your guitar.
The DEEP (Bass) control
Think of this as more of an overall thickening to the sound. Start with this all the way down and after finding the Volume and Sing levels you want then increase the Deep control until you find the thickness you want.
