When we released our original Tone King Imperial combo 20 years ago, we felt we had made one of the best-sounding American-voiced amps on the market. But... thanks to the experience and knowledge that two decades of amp building offers, we knew we could do better. Tone King is proud to offer the new and improved Imperial MKII. Everything you know and love about the original is still there. The spanky blackface-style voice, the gritty tweed tones, all of it; however, the MKII takes it all a few steps further. Its two channels have been tuned for better-sounding overdrive, a smoother top end, and more harmonic complexity. The amp's vintage-voiced tube reverb and tremolo will cause you to question whether you’re actually playing a vintage amp. Thanks to the Imperial MKII’s onboard Ironman II power attenuator, you can get all of these tube-driven tones at any volume. When your company is built upon the legacy of an amp like the Imperial, you’d better be sure you honor your past while always improving. With the Imperial MKII, we did.

Onboard Spring Reverb and Tremolo

_x000D_

Spring reverb and bias-modulated tremolo are two sounds that define the tone of many vintage American-voiced combo amps. We think, with its tube-driven circuits and old-school control, you’ll find the Imperial MKII gloriously re-creates those thick, splashing, pulsating tones.

• Bias modulation tremolo circuit delivers vintage-style pulse

• Tube driven spring reverb with wide-ranging control
