Tone King Royalist Preamp

The Tone King Royalist Preamp brings the legendary roar of British rock history directly to your pedalboard. This high-voltage, tri-tube powerhouse is meticulously engineered to replicate the circuit of the Royalist MKIII amplifier. By utilizing three 12AX7 tubes running at authentic high voltages, it delivers the unmistakable touch sensitivity, harmonic bloom, and sag that defined the "golden era" of British amplification. Whether you are looking for the sweet chime of a JTM45 or the aggressive, mid-forward punch of a 1970s Super Lead, this pedal provides the genuine tube-driven response that digital emulations often miss.

Construction-wise, the Royalist Preamp is a masterclass in versatility and ruggedness. It features two independent channels, each equipped with era-accurate tone stacks: the top channel is voiced after the vintage JTM45/Bassman EQ, while the bottom channel utilizes a later-era British Lead circuit. A standout feature is the "Zero Watt Power Amp," a dedicated phase inverter circuit that captures the interaction between the preamp and power section. Housed in a durable chassis with comprehensive I/O—including balanced XLR outs and a stereo FX loop—it is built to be the centerpiece of a professional touring rig or a high-end studio setup.

What truly sets this preamp apart is its integration of modern technology with vintage soul. Each channel features a three-way voicing selector (1964, 1967, and 1970) and a FAT switch to tailor the low-end response to your specific guitar. With the addition of a built-in IR loader featuring curated OwnHammer impulse responses and MIDI programmability for up to 128 presets, the Royalist Preamp offers a complete "amp-in-a-box" solution. It allows you to carry decades of iconic British heritage in your gig bag without sacrificing the organic feel of a real tube amplifier.
