IN MORE DETAIL
Born into a musical family in South Carolina, Marcus King grew up surrounded by Southern rock, gospel and the blues. By his teens he was touring with The Marcus King Band, earning acclaim for his voice as much as his guitar work. His playing fuses deep soul, classic rock and improvisational jazz, with phrasing that’s emotional rather than showy.
That approach to tone led to a collaboration with Orange USA, culminating in the MK Ultra, a 30-Watt, single-channel head built for touch-sensitive dynamics and rich harmonic drive. Designed around Marcus’s feel-first brief, it stays sweet when clean and blooms when pushed, following every nuance of his right hand. The result is a signature amplifier that embodies his musical DNA — soulful, reactive and bursting with character.
Soul-driven tone
Marcus King’s tone lives at the meeting point of grit and grace: searing one moment, tender the next. The MK Ultra was built to channel that range, offering huge dynamic sweep and rich harmonic content. Whether he’s digging in with a slide or easing back into glassy chords, the amp responds like a living instrument. It’s a design rooted in emotion, not excess — tone that feels alive under the fingers.
Built for feel, not flash
What defines Marcus King isn’t speed or flashiness, but feel. Every note carries intent, and the MK Ultra amplifies that honesty. Its single-channel simplicity and 6L6-driven design make it responsive, unfiltered and unmistakably human. Like Marcus himself, it thrives on subtlety and soul, rewarding players who play with touch rather than force.
Vintage spirit with modern muscle
The MK Ultra bridges eras: classic tube warmth meets modern reliability. Marcus wanted an amp that could handle studio nuance and stage power without compromise. Together with Orange, he crafted an amplifier that captures the timeless essence of American tone through a distinctly British lens. It’s the sound of tradition evolving: expressive, fearless, and full of life, just like Marcus King.
