Tone King Imperial Preamp High Voltage Tri-Tube Preamp 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. 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.

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.

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.

Impulse Response (IR) Cabinet & Power Amp Sim

The Imperial Preamp pedal's low latency IR and power amp simulation technology delivers its tube tones directly to the front of house or your interface. That’s especially evident in the 15 included OwnHammer-made IRs. Each channel has three of our favorites, preloaded, and selectable via dual 3-way toggle switches.

There are 12 additional IRs to choose from in the included Tone King Editor software (powered by Synergy) which are easy to swap in and out of the pedal's six available slots. You can also disengage the onboard IR loader entirely to use the preamp with an external IR loader or powered cabinet.

Tone King Editor Software

You can assign the Reverb, Tremolo and IR to each of the channels right on the pedal itself, making it a powerful and easy-to-use sonic tool. Tone King offers an Editor software, powered by Synergy, which takes the Pre-Amp's capabilities to another level, allowing you to fine-tune all of the preamp's digitally controlled parameters and save them in up to 128 MIDI presets
