This new limited edition  Orange Marcus King MK Ultra signature amp head has a super simple control layout. One that ultimately aims to give you great tone. This built in the USA, British amplifier has been designed to get Marcus his sound, and has a pretty unique circuit.

Orange Marcus King MK Ultra

The Orange Marcus King MK Ultra is a 30 Watt all tube amp, based around a pair of 12AX7 preamp tubes, paired with two 6L6GC power tubes that are cathode-biased. Where it really stands out is the unique, and super simple control layout. This consists three controls,  a Volume knob which Orange states is as much a tone control as the Sing (treble) and Deep (bass) control. Yes, you only have three knobs on the front of this amp head, and really that is all you need.

The front panel looks pretty spare, as the only other features are the single input along with a Standby and an On/Off switch. Minimal is certainly the feel of this front panel. I’m personally more than happy with a simple amp layout and so this looks interesting.

Tone

Being a cathode-biased amp it is described by Orange as being urgent at lower volumes. Expect it to react well to volume and tone changes from your guitar. Certainly it will be an amp that will react well to your guitars volume knob, which can be a lot of fun. Plus, it should also fair very well as a platform for effects pedals. Orange has designed it so that any increase of the main amp volume knob you will lead to more saturation.  As those 6L6 power tubes start to break up, it will reward you with a very playable, spongy attack.  Again, this all sounds like my kind of amp.

Signature Sound

Round the back you get outputs on 4, 8 and 16 Ohm, so this head will work with all your common speaker cabinet types. It is a very specific amp and was designed for Marcus King, and if you have one of his signature Gibson ES-345 models, you could try to emulate his tone. I suspect this limited edition amp will have a limited appeal, as it is very specific. That isn’t to say that I think that is a bad thing. In fact, I really like the sound of it, and certainly can see its appeal.

    Doh!

    What a terrible product name! MKUltra was the name of an illegal program run by the CIA to run all sorts of terrible tests on human subjects to try to erase people’s minds.

      But the name is “Marcus King MK Ultra ” and not the “MKUltra” or “MK-Ultra” associated with that CIA program.

      Maybe someone at Orange didn’t think to check the name for any issues? Just unlucky I guess, as I can’t see the brand or Marcus wanting to associate with LSD based psychological torture.

        That’s still unprofessional of Orange, as the very first search results for “MK Ultra” will spell out the CIA association.

        Reminds me of the Mitsubishi Pajero. A Spanish word with all kinds of meanings, none of them positive.
