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

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.

Expanding Your Rig’s Capabilities.

The Imperial Preamp Pedal is the perfect DI recording and performing solution. But that’s just scratching the surface.

Networking with Other Effects-Loop-Equipped Preamp Pedals.

Create the ultimate pedalboard-based rig with other preamp pedals (with effects loops). Using the same 3-cable method, you get both Imperial channels, your other preamp’s tones, the Imperial’s stereo effects loop, and its onboard IRs. Additionally, you can assign the Imperial’s spring reverb and tremolo effects to your other preamp channels.

Add Channels to Your Current Guitar Amplifier.

A standout feature of the Imperial preamp pedal is its ability to easily integrate with your existing amplifiers (must have a series effects loop). A straightforward 3-cable connection is all it takes, and you can instantly alternate between the Imperial Preamp as your amp’s front end or your amp’s preamp channels.
