Tone King Royalist Preamp

High Voltage Tri-Tube British Preamp Pedal

The Sound of British Rock Royalty - Now on Your Pedalboard

The Royalist Tube Preamp Pedal captures the soul of Tone King’s beloved Royalist MKIII amplifier - the company’s most authentic take on the golden age of British tone. From the sweet, singing JTM45, through the unmistakable Plexi crunch, to the searing drive of the Super Lead, this high-voltage tri-tube preamp pedal delivers the full spectrum of British rock attitude in a compact, pedalboard-friendly format.

Running on three 12AX7 tubes at proper high voltages, the Royalist Preamp brings the complete touch sensitivity, harmonic bloom, and dynamic punch of the Royalist MKIII amp to your pedalboard. Each of its two independent channels features the amp’s FAT switch and three-way 1964/1967/1970 voicing selector, faithfully reproducing the gain structure, tone stack, and feel of the original circuits. Whether you’re chasing sparkling cleans, punchy crunch, or molten roar, the Royalist Preamp delivers the unmistakable voice of British rock, anywhere, at any volume.

Three Eras of Iconic British Tone

Each channel of the Royalist Preamp offers its own three-position voicing switch, mirroring the evolution of the British amp sound across decades:

1964 - Smooth top end, lower gain, and a balanced, vintage warmth inspired by early British blues amps.

1967 - Crisp treble response, bold midrange, and the aggressive bite that defined rock’s formative years.

1970 - Increased gain and tightness for that unmistakable, high-energy crunch of arena-ready hard rock.

Pair these voicings with each channel’s FAT switch option to add body and low-end warmth to single-coil guitars or enhance sustain and punch with humbuckers.

Era Accurate Tone Stacks

The Royalist features two identical channels, each voiced with its own distinct tone stack. The top channel uses a vintage-accurate JTM45 / Bassman / Super Bass inspired EQ. The bottom channel reflects a later-era British Lead tone stack. 

While the two channels can be dialed remarkably close, their subtle differences give players two authentic British flavors—one tight and articulate, the other more mid forward.

Built-In Zero Watt Power Amp — Phase Inverter

The Royalist Preamp includes Tone King’s “Zero Watt Power Amp,” a genuine phase inverter circuit powered by one of its three 12AX7 tubes. This design captures the Royalist’s harmonic depth and dynamic interaction between preamp and power stage — a key ingredient of true British tone that most preamp pedals can’t replicate. The result is the full experience of an overdriven Royalist power section, without the ear-splitting volume.

Impulse Response (IR) Cabinet & Power Amp Sim

The Royalist Preamp Pedal features Tone King’s low-latency IR and power amp simulation engine, offering direct output to FOH, recording interfaces, or headphones with stunning realism. Preloaded with a curated selection of OwnHammer IRs listed below, each channel includes a 3-way IR selector for instant tonal changes. 

OH 412 Pinstripe H25: Celestion G12H-25's from 1967 captured in a pinstripe 1982B 4x12 cabinet by Kevin Rowe of OwnHammer using Shure SM57, Telefunken MD421, and Royer 121 microphones through mid-late 1970's API 312 preamps.

OH 112 Imperial TK1660: Tone King 1660 captured in a Tone King Imperial 1x12 combo by Kevin Rowe of OwnHammer using Shure SM57, Neumann U87, and Royer 121 microphones through mid-late 1970's API 312 preamps.

OH 412 M75BB: 16-ohm, 1777 cone Celestion "black back" G12M-75's from 1975 captured in a 412 cabinet by Kevin Rowe of OwnHammer using Shure SM57 and Sennheiser MD421 microphones through mid-late 1970's API 312 preamps.

There are 20 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 - Deep Control, Modern Flexibility

The included Tone King Editor software unlocks deep editing capabilities for digital parameters. Save and recall up to 128 presets via MIDI, assign IRs per channel, fine-tune HF and LP filters, and configure reverb, or FX loop assignments — all in one intuitive interface.

Savable Parameters

  • Channel switching and bypass states
  • Easily load your own IRs and manage your IR library
  • IR bypass and power amp simulation options
  • HF Comp and Low-Pass filters
  • Access all 20 included OwnHammer IRs

Expanding Your Rig

The Royalist Preamp Pedal is equally at home on stage, in the studio, or integrated with your favorite amp.


Add Channels to Your Amp:

Use the 3-cable method with any amp that has a series effects loop to instantly add two channels of British tube tone to your existing rig.


Combine with Other Preamps:

Link multiple effects-loop-equipped preamp pedals to build an ultimate hybrid system. Assign the Royalist’s IRs and power amp emulation to other preamps, or route its reactive output into a separate power amp and cabinet for the real-air experience.


The Sound of British Heritage, Reborn for the Modern Player

From the club stages of the ‘60s to the arenas of the ‘70s, the sound of British rock has defined generations of guitar tone. Now, with the Royalist Tube Preamp Pedal, that legacy lives on — delivering the roar, chime, and harmonic richness of those legendary amplifiers in a compact, high-voltage, pedalboard-ready design.

    Great vacuum, but it only works on 2.4 GHz Wi-Fi
    Style: L50 SES
    I missed the last line on the description that states in only works on 2.4 GHz Wi-Fi. I have AT&T fiber and the router they installed only runs on 5.0 GHz. The vacuum still works, but without all of the fancy conveniences. Just be aware of this and if you are not familiar with what it means, check before you purchase one. This is the only reason I am giving it a 4 and not a 5. It is my fault for missing it, so just be aware.

    Great vacuum!!
    Style: L50 SES
    I love this vacuum. I had to work a little to get the map right for it, but it is great. We have allergies and it helps so much and saves so much time. It does take a while to do the whole house, but I have it programmed to run while we are at work and it’s so nice to come home to a freshly vacuumed house.

    Eufy dropped the ball on this vacuum
    Style: L50 SES
    I’ll start by saying the reason I purchased this vacuum, is because I have a Eufy 25c robot vacuum that is very dependable. I decided I wanted an upgrade because the 25C was great for cleaning, but I had to empty it way too often. I just knew I would love the L50 SES. I thought it was just what I was looking for a self emptying robot vacuum with a 60 day fill capacity. Allowing 2 months before I needed to touch my vacuum. Here’s where things went wrong. I never got a chance to test the vacuum because it wouldn’t connect to my WiFi and I tried everything. Now this wouldn’t have been a problem if the L50 came with a remote control like the 25C. Unfortunately I had to rely on the App and since the L50 couldn’t connect to my WiFi, I couldn’t control the vacuum. The reason I gave 2 stars is because the customer service at Eufy is awesome. I was given the option to replace the vacuum with a new one but after researching the L50 i decided to return it for a refund. Apparently this model has a defect, because I found so many negative reviews about the same issue with the same model. The thing is I never read reviews because I have a Eufy smart scale, 25C robot vacuum and an Eufy security system and everything works perfectly. So in the end I purchased a Shark Matrix Self emptying robot vacuum and a Shark self emptying stick vacuum. If Shark’s vacuum preforms well, Eufy might have lost a valued customer. I hope this review helps someone make a informed decision. By the way Eufy self emptying vacuum needs replacement bags and the Shark Matrix robot vacuum doesn’t need bags. I will say the suction and design on the Eufy L50 SES was great.

    Much better than the old model.
    Style: L50 SES
    I had an old s11 that finally died. This one is much better. It maps the house and follows a snake pattern. Once the mapping is finished you can select what rooms you want to clean. I like the self emptying feature. Plenty of battery life.

    Good performance, flaky Wi-Fi connection
    Style: L50 SES
    The L50 physically works great - it does a good job of picking up dust and dirt at the end of the day. The pathfinder and route planning algorithm is fairly efficient at determining the best way to clean a room. Sometimes it kicks around bits of dust with its spinning brush without picking it up, but it's not often. What has been terrible, however, is the Wi-Fi support. Since our provider disabled 2.4 GHz support from their router modem without notice, I use a Mac Mini to supply the 2.4 GHz signal, and even though the Eufy is next to it and my phone gets full signal strength, it still can't connect to it half the time. After it fails to connect, it needs to be restarted or even reset to try to get the connection again. Support doesn't seem to be helpful in offering a solution.
