High Voltage Tri-Tube Preamp Pedal
The Heart of the Imperial MKII, Now on Your Pedalboard

About the pedal.

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.

Legendary Vintage Tube Amp Tones.

The Imperial Preamp Pedal features two distinct channels, each mirroring the ’50s and ’60s flavors of the Imperial MKII.

British-flavored rock.

The Lead Channel is inspired by the iconic tweed amps of the ’50s’ with the ability to glide between warm articulate cleans and aggressive midrange bark. This channel’s Mid-Bite control adds a further layer of tone shaping, focusing the low-end, while adding high-end presence and gain for a British-flavored rock crunch.

Classic ’60s.

The Rhythm Channel evokes the essence of a classic ’60s blackface combo’s pristine cleans with a touch-sensitive response that transitions smoothly into overdrive.

Built-In Zero Watt Poweramp – Phase Inverter.

The Imperial Pre-Amp Pedal includes the exact phase inverter circuitry of the actual Imperial MKII amp, utilizing one of its three 12AX7 tubes. This built-in “0 watt poweramp” authentically provides the harmonic and dynamic content of the Tone King poweramp section. This revolutionary design is the cornerstone that delivers the ENTIRE Imperial MKII experience right on your pedal board.

Stereo Convolution Spring Reverb & Stereo Tremolo.

Like its namesake amp, the Imperial Preamp boasts foot-switchable spring reverb and tremolo (digital on the preamp pedal) which are assignable to each channel. A signature of the Tone King Imperial MKII tube amplifier, these era-correct effects add dimension and movement while transporting you to a golden age of electric guitar tone.
