Tone King Royce Preamp

Classic British Chime, Reimagined!

The Tone King ROYCE brings the unmistakable sound and feel of classic British AC amplifiers to a sophisticated, pedalboard-friendly tube preamp. Inspired by the legendary combos that helped define the British Invasion, the ROYCE captures their shimmering highs, rich harmonic complexity, and dynamic touch response through a genuine high-voltage tube circuit. With two independent channels, built-in effects, advanced cabinet simulation, and extensive routing possibilities, the ROYCE combines vintage-inspired tone with the flexibility demanded by modern guitarists.

At the heart of the ROYCE are three 12AX7 tubes operating at high voltage, delivering the depth, responsiveness, and natural saturation associated with a great tube amplifier. Rather than relying exclusively on digital modeling, the ROYCE uses an authentic tube preamp alongside Tone King's Zero-Watt Power Amp, which incorporates a genuine phase inverter stage to reproduce the interaction between a preamp and power section. The result is an organic playing experience, with natural compression, harmonically rich overdrive, and exceptional sensitivity to picking dynamics and guitar volume adjustments.

Two independent channels offer the choice between Normal and Top Boost modes, each with its own set of controls. Normal mode delivers bold, full-bodied clean tones with warm highs, substantial low end, and excellent harmonic depth. Switching to Top Boost introduces additional gain, enhanced high-frequency sparkle, and greater harmonic complexity, making it possible to move from articulate edge-of-breakup sounds to singing, saturated leads. Each channel features dedicated Attenuation, Cut, Treble, Bass, Middle, and Volume controls, allowing you to shape your sound with precision.

Vintage-Inspired Effects & Cabinet Simulation

To complete the classic amplifier experience, the ROYCE includes lush stereo spring reverb and expressive stereo tremolo. The convolution-based spring reverb offers adjustable Level and Dwell controls, while the tremolo provides Speed and Depth adjustments. Both effects can be assigned independently to either channel, making it easy to create everything from subtle vintage ambience to expansive, dimensional stereo textures.

For guitarists who want to perform or record without a traditional amplifier, the ROYCE features Tone King's low-latency impulse response cabinet simulation and power amp emulation. Each channel includes a dedicated three-position IR selector, providing immediate access to your preferred cabinet sounds. Twenty professionally captured OwnHammer impulse responses are included, with additional IR loading and management available through the SYNERGY Editor software. The onboard IR processing can also be bypassed when using an external cabinet simulator or power amplifier.

Modern Connectivity & Seamless Rig Integration

The ROYCE is equally comfortable in a traditional amplifier setup or a fully direct rig. Dual balanced XLR outputs allow direct connection to a mixing console, recording interface, or front-of-house system, while a dedicated headphone output makes silent practice and recording simple. A stereo series effects loop provides convenient integration for your favorite delay, reverb, and modulation pedals, and the extensive routing options allow the ROYCE to add two additional channels to an existing amplifier equipped with a series effects loop.

For more advanced setups, the included SYNERGY Editor software provides extensive control over the pedal's functions through its USB-C connection. Players can manage cabinet impulse responses, configure power amp simulation and filtering, adjust effect assignments, and customize signal routing. MIDI connectivity allows up to 128 presets to be saved and recalled, making the ROYCE a powerful centerpiece for sophisticated pedalboard systems and live performances.

Combining the unmistakable chime of classic British AC amplifiers with genuine high-voltage tube circuitry, Tone King's renowned attenuation technology, and modern direct-recording capabilities, the Tone King ROYCE delivers an exceptionally versatile amplifier experience in a compact pedal format. From shimmering cleans and touch-sensitive breakup to rich, harmonically complex overdrive, the ROYCE brings the sound and response of a world-class tube amplifier wherever your music takes you.
