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 4×12
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 1×12 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.
