For nearly two decades, Tone King has been synonymous with premium American tube tone, and no amplifier better defines their legacy than the Imperial MKII. From the glassy spank of vintage Blackface cleans to the gritty breakup of the best Tweed tones, the Imperial delivers touch-sensitive dynamics and sweet harmonic complexity. Now, through a collaboration with Synergy, the Tone King Imperial experience has been brought to the modular preamp format.

The Rhythm channel captures the shimmering highs and round low end of a great Blackface-era amp, perfect for crisp chords, blues-inspired leads, and lush clean textures. The Lead channel is voiced after a mid-'50s Tweed amp pushed into glorious overdrive. Each channel features independent tone shaping, Volume, and Attenuation controls.

A vintage-style true analog bias tremolo delivers pulsing, organic movement and can be assigned to either or both channels. Synergy's "Zero Watt Poweramp" technology incorporates the exact phase inverter circuitry from the Imperial MKII amplifier, so the module responds with the same blooming harmonics and dynamic nuance as its full-sized counterpart.
