The Tone King Imperial Preamp Pedal delivers legendary vintage American tube tone with modern control. Featuring two channels mirroring '50s tweed and '60s blackface tones, built-in zero watt poweramp, stereo convolution spring reverb and tremolo, and low-latency impulse response technology. MIDI programmable with up to 128 presets for instant recall.
The Imperial All-Tube Preamp pedal delivers Tone Kingās 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 '50sā 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 ā0 watt powerampā 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. Thatās 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.
OH 112 Imperial TK1660: Tone King 1660 speaker in a Tone King Imperial 1x12 combo. Captured using a Shure SM57, a Neumann U87, and a Royer 121 through '70s API 312 preamps.
OH 212 Class A Blue: Celestion Blues from 1963 in a Vox AC30 2x12 combo. Captured using a Shure SM57, a Neumann U87, and a Royer 121 through '70s API 312 preamps.
OH 412 Basketweave M25: Celestion G12M-25 speakers from 1971 in a basket-weave 1960B 4x12 cabinet. Captured using a Shure SM57, Telefunken MD421, and Royer 121.
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
- Control the independent power amp simulation HF Comp and Low-Pass filters
- Access all 15 included OwnHammer IRs⢠Easily load your own IRs and manage your IR library
- Assign any of your IRs to the pedal's six available slots (three per channel)⢠Control your reverb, reverb tails, tremolo and effects loop bypass settings⢠Save these settings to up to 128 presets for instant recall via MIDI
The Tone King Editor software also unlocks all of the Imperial Preamp's modern control. Fully MIDI-capable, you can save your presets and access them instantly with a MIDI pedalboard controller or the laptop running your entire show. It is the perfect marriage of modern control and classic tube tone.
Expanding Your Rig's Capabilities
The Imperial Preamp Pedal is the perfect DI recording and performing solution. But that's just scratching the surface.
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.
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 preampās 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.
Classic American Tube Tone for Every Stage & Studio
Whether you're a gigging musician, a recording artist, or simply a tone enthusiast, the Tone King Imperial Preamp pedal offers endless possibilities. Use it as a standalone preamp for recording or for silent stages and practice, add its two channels to your existing amplifier, pair it with a power amp and cabinet to move some air, or combine it with other preamp pedals for an even wider range of pedalboard-based tones.
Tone King Imperial Preamp Pedal is the ultimate marriage of legendary, vintage American tube tone and modern control.

This legendary vintage rack unit will inspire you to think about effects with a new perspective.
When guitarists think of effects, we usually jump straight to stompboxesātheyāre part of the culture! And besides, footswitches have real benefits when your hands are otherwise occupied. But real-time toggling isnāt always important. In the recording studio, where weāre often crafting sounds for each section of a song individually, thereās little reason to avoid rack gear and its possibilities. Enter the iconic Eventide H3000 (and its massive creative potential).
When it debuted in 1987, the H3000 was marketed as an āintelligent pitch-changerā that could generate stereo harmonies in a user-specified key. This was heady stuff in the ā80s! But while diatonic harmonizing grabbed the headlines, subtler uses of this pitch-shifter cemented its legacy. Patch 231 MICROPITCHSHIFT, for example, is a big reason the H3000 persists in racks everywhere. Itās essentially a pair of very short, single-repeat delays: The left side is pitched slightly up while the right side is pitched slightly down (default is ±9 cents). The resulting tripling/thickening effect has long been a mix-engineer staple for pop vocals, and itās also my first call when I want a stereo chorus for guitar.
The second-gen H3000S, introduced the following year, cemented the deviceās guitar bona fides. Early-adopter Steve Vai was such a proponent of the first edition that Eventide asked him to contribute 48 signature sounds for the new model (patches 700-747). Still-later revisions like the H3000B and H3000D/SE added even more functionality, but these days itās not too important which model you have. Comprehensive EPROM chips containing every patch from all generations of H3000 (plus the later H3500) are readily available for a modest cost, and are a fairly straightforward install.
In addition to pitch-shifting, there are excellent modulation effects and reverbs (like patch 211 CANYON), plus presets inspired by other classic Eventide boxes, like the patch 513 INSTANT PHASER. A comprehensive accounting of the H3000ās capabilities would be tedious, but suffice to say that even the stock presets get deliciously far afield. There are pitch-shifting reverbs that sound like fever-dream ancestors of Strymonās āshimmerā effect. There are backwards-guitar simulators, multiple extraterrestrial voices, peculiar foreshadows of the EarthQuaker Devices Arpanoid and Rainbow Machine (check out patch 208 BIZARRMONIZER), and even button-triggered Foley effects that require no input signal (including a siren, helicopter, tank, submarine, ocean waves, thunder, and wind). If youāre ever without your deck of Oblique Strategies cards, the H3000ās singular knob makes a pretty good substitute. (Spin the big wheel and find out what youāve won!)
āIf youāre ever without your deck of Oblique Strategies cards, the H3000ās singular knob makes a pretty good substitute.ā
But thereās another, more pedestrian reason I tend to reach for the H3000 and its rackmount relatives in the studio: I like to do certain types of processing after the mic. Itās easy to overlook, but guitar speakers are signal processors in their own right. They roll off high and low end, they distort when pushed, and the cabinets in which theyāre mounted introduce resonances. While this type of de facto processing often flatters the guitar itself, it isnāt always advantageous for effects.
Effects loops allow time-based effects to be placed after preamp distortion, but I like to go one further. By miking the amp first and then sending signal to effects in parallel, I can get full bandwidth from the airy reverbs and radical pitched-up effects the H3000 can offerāand I can get it in stereo, printed to its own track, allowing the wet/dry balance to be revisited later, if needed. If a sound needs to be reproduced live, thatās a problem for later. (Something evocative enough can usually be extracted from a pedal-form descendant like the Eventide H90.)
Like most vintage gear, the H3000 has some endearing quirks. Even as it knowingly preserves glitches from earlier Eventide harmonizers (patch 217 DUAL H910s), it betrays its age with a few idiosyncrasies of its own. Extreme pitch-shifting exhibits a lot of aliasing (think: bit-crusher sounds), and the analog Murata filter modules impart a hint of warmth that many plug-in versions donāt quite capture. (They also have a habit of leaking black goo all over the motherboard!) Itās all part of the charm of the unit, beloved by its adherents. (Well, maybe not the leaking goo!)
In 2025, many guitarists wonāt be eager to care for what is essentially an expensive, cranky, decades-old computer. Even the excitement of occasional tantalum capacitor explosions is unlikely to win them over! Fortunately, some great software emulations existāEventideās own plugin even models the behavior of the Murata filters. But hardware offers the full hands-on experience, so next time you spot an old H3000 in a rack somewhereāand youāve got the timeāfire it up, wait for the distinctive āclickā of its relays, spin the knob, and start digging.

The luthierās stash.
There is more to a guitar than just the details.
A guitar is not simply a collection of wood, wire, and metalāit is an act of faith. Faith that a slab of lumber can be coaxed to sing, and that magnets and copper wire can capture something as expansive as human emotion. While itās comforting to think that tone can be calculated like a tax return, the truth is far messier. A guitar is a living argument between its componentsāan uneasy alliance of materials and craftsmanship. When it works, itās glorious.
The Uncooperative Nature of Wood
For me it all starts with the wood. Not just the species, but the piece. Despite what spec sheets and tonewood debates would have you believe, no two boards are the same. One piece of ash might have a bright, airy ring, while another from the same tree might sound like it spent a hard winter in a muddy ditch.
Builders know this, which is why youāll occasionally catch one tapping on a rough blank, head cocked like a bird listening. Theyāre not crazy. Theyāre hunting for a lively, responsive quality that makes the wood feel awake in your hands. But wood is less than half the battle. So many guitarists make the mistake of buying the lumber instead of the luthier.
Pickups: Magnetic Hopes and Dreams
The engine of the guitar, pickups are the part that allegedly defines the electric guitarās voice. Sure, swapping pickups will alter the tonality, to use a color metaphor, but they can only translate whatās already there, and thereās little percentage in trying to wake the dead. Yet, pickups do matter. A PAF-style might offer more harmonic complexity, or an overwound single-coil may bring some extra snarl, but hereās the thing: Two pickups made to the same specs can still sound different. The wire tension, the winding pattern, or even the temperature on the assembly line that day all add tiny variables that the spec sheet doesnāt mention. Donāt even get me started about the unrepeatability of āhand-scatter winding,ā unless youāre a compulsive gambler.
āOne piece of ash might have a bright, airy ring, while another from the same tree might sound like it spent a hard winter in a muddy ditch.ā
Wires, Caps, and Wishful Thinking
Inside the control cavity, the pots and capacitors await, quietly shaping your tone whether you notice them or not. A potentiometer swap can make your volume taper feel like an on/off switch or smooth as an aged Tennessee whiskey. A capacitor change can make or break the tone controlās usefulness. Itās subtle, but noticeable. The kind of detail that sends people down the rabbit hole of swapping $3 capacitors for $50 āvintage-specā caps, just to see if they can āfeelā the mojo of the 1950s.
Hardware: The Unsung Saboteur
Bridges, nuts, tuners, and tailpieces are occasionally credited for their sonic contributions, but theyāre quietly running the show. A steel block reflects and resonates differently than a die-cast zinc or aluminum bridge. Sloppy threads on bridge studs can weigh in, just as plate-style bridges can couple firmly to the body. Tuning machines can influence not just tuning stability, but their weight can alter the way the headstock itself vibrates.
Itās All Connected
Then thereās the neck jointāthe place where sustain goes to die. A tight neck pocket allows the energy to transfer efficiently. A sloppy fit? Some credit it for creating the infamous cluck and twang of Fender guitars, so pick your poison. One of the most important specs is scale length. A longer scale not only creates more string tension, it also requires the frets to be further apart. This changes the feel and the sound. A shorter scale seems to diminish bright overtones, accentuating the lows and mids. Scale length has a definite effect on where the neck joins the body and the position of the bridge, where compromises must be made in a guitarās overall design. There are so many choices, and just as many opportunities to miss the mark. Itās like driving without a map unless youāve been there before.
Alchemy, Not Arithmetic
At the end of the day, a guitarās greatness doesnāt come from its spec sheet. Itās not about the wood species or the coil-wire gauge. Itās about how it all conspires to either soar or sink. Two guitars, built to identical specs, can feel like long-lost soulmates or total strangers. All of these factors are why mix-and-match mods are a long game that can eventually pay off. But thatās the mystery of it. You canāt build magic from a parts list. You canāt buy mojo by the pound. A guitar is more than the sum of its partsāitās a sometimes unpredictable collaboration of materials, choices, and human touch. And sometimes, whether in the hands of an experienced builder or a dedicated tinkerer, it just works.
