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.
