Independent shopping perspective
Tone King’s Imperial Preamp puts the Imperial MKII’s preamp section and phase-inverter circuitry on a pedalboard. Rhythm and Lead channels cover the model’s blackface- and tweed-inspired voices, with Mid-Bite on the Lead channel for added tonal shaping. Three high-voltage 12AX7 tubes drive the circuit. Stereo spring reverb, tremolo, and onboard cabinet IRs let it handle a direct route to a PA or audio interface, while MIDI and the Tone King Editor support preset-based rigs.
