The Imperial All-Tube Preamp pedal delivers Tone King’s legendary MKII amplifier's '50s tweed, '60s blackface, and vintage British rock tones in a compact, pedalboard-friendly format. It features the exact preamp section and phase inverter circuitry of the Imperial MKII amp, as well as Reverb, Tremolo and Attenuation, resulting in a pedal that sings with harmonic richness and blooming touch response. Powered by three 12AX7 preamp tubes running at high voltage, this preamp delivers the amp's sound, responsiveness, and exquisite interaction with your pickups and effects. The onboard, low-latency impulse response (IR) loader (per channel), Headphones, easy integration and expansion with your existing gear, and MIDI capabilities, takes these iconic tones into the new era of guitar playing.
