IMPERIAL MK II.

Vintage American tone for modern players

About the amp.

Tone King is proud to offer the Imperial MKII. From a spanky blackface-style voice to ‘50s-era tweed grit, you’ll find all of the most iconic American tube tones residing in this 1 x 12”, 20-watt combo. And with modern appointments, such as an onboard Ironman II power attenuator, and tube-driven effects, the Imperial MKII is the perfect old-school platform for modern players.

Key features:

  • Footswitchable 2-channel design (rhythm, lead)
  • Ironman II reactive attenuation
  • Bias modulation tremolo circuit delivers vintage-style pulse
  • Tube driven spring reverb with wide-ranging control
  • Custom-voiced 12” Eminence speaker

Iconic American tones.

Though labeled Rhythm and Lead, the Imperial MKII’s dual foot-switchable channels could very well be called blackface and tweed. The higher-headroom Rhythm channel speaks with the crystal-clear body and presence of the mid-’60s most popular amps. The Lead channel brings on the spongy midrange response and sustain of the most beloved ‘50s designs. And both feature straightforward 3-band EQ control, for to-die-for tone on any setting.

Ironman II reactive attenuation.

The Ironman II reactive power attenuator gives Tone King amplifiers increased flexibility for any gig, session, or rehearsal. And thanks to its reactive load technology and HF Compensation, it does it while always maintaining your cranked amp tone and feel. Go ahead, crank your amp to the sweet spot then reign in the volume for thick, rich tone at usable levels.

Spring reverb and bias-modulated tremolo.

Spring reverb and bias-modulated tremolo have helped define the tone of many vintage, American-voiced combo amps. We have gone into painstaking detail to re-create those same thick, splashing, pulsating tones. And we think you’ll find our tube-driven circuits and old-school control perfectly capture the sound and character of the originals.

Custom-voiced Eminence speaker.

Every Tone King combo amplifier is outfitted with a 12” Eminence speaker, voiced to deliver the top-shelf tone our brand demands. As soon as you hit your first notes, you’ll experience the detailed overtones, warm lows, and vocal-like mids all displaying pristine sonic detail.

Built for tone, built to last.

From the tolex to the wiring, every Tone King amplifier is constructed with a passion for tone and reliability, right here in the US. We use only premium baltic birch in the construction of our cabinets and amp shells. And every amp is meticulously hand-built to deliver top-notch tone every time you plug in.

A style all our own.

The first thing that often jumps out about Tone King amplifiers is our stage-ready presentation. When you’re as passionate about tone as we are, there’s no reason to hide in the background.
