The Tone King Royce Preamp brings the legendary sound and feel of classic AC-style amps to your pedalboard. Running on three high-voltage 12AX7 valves, it delivers the chime, richness and dynamic response that have made these British circuits so iconic. With two independent channels, built-in effects and extensive connectivity, it’s a super-flexible solution whether you’re playing live, recording or building a more complex rig. Two channels, four classic AC voices Each of the Royce Preamp’s two channels features a Normal/Top Boost switch, giving you access to a wide range of classic AC-inspired tones. Normal mode delivers punchy cleans with a thick low end and warm highs, while Top Boost mode adds extra gain and chime for everything from edge-of-breakup sparkle to singing lead sounds. Because both channels offer the same controls and voicings, you can configure them however you like. Authentic tube feel & built-in effects The Tone King Royce Preamp also features Tone King’s Zero-Watt Power Amp tech, driven by one of its three 12AX7 valves. This recreates the interaction between a preamp, phase inverter and power section, helping notes compress naturally and respond dynamically to your playing and guitar volume changes. Stereo reverb and tremolo are also onboard, providing everything from subtle ambience and vintage-style pulse to expansive stereo textures without the need for additional pedals. Ready for modern rigs This powerful pedalboard amp is packed with features aimed at today’s guitarist. Dual balanced XLR outputs with built-in low-latency IR and power amp simulation allow for direct connection to PA systems and recording interfaces, while MIDI support enables preset recall and integration with larger switching systems. A stereo series effects loop is included for time-based and modulation effects, alongside a headphone output for silent practice and recording. Synergy Editor software The included Synergy Editor software unlocks deeper editing, access to 20 included OwnHammer IRs and storage for up to 128 MIDI-recallable presets. Here are all of the 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. Assign any of your IRs to the pedal’s six available slots (three per channel). Reverb, reverb tails and effects loop bypass routing. Save these settings to up to 128 presets for instant recall via MIDI. Key Features Three 12AX7 preamp valves: Running on three genuine 12AX7 tubes at high voltage, the Royce delivers the dynamic feel, harmonic richness and touch-sensitive response that players expect from premium valve-driven gear. Two independent channels with DI: Dial in and switch between two distinct sounds with ease, while built-in direct connectivity makes it simple to go straight to a PA, recording interface or monitoring setup. Built-in Zero-Watt Power Amp tech: This recreates the interaction between a preamp, phase inverter and power section for a more authentic amp-like playing experience. Extensive EQ & attenuation controls: Each channel is equipped with Attenuation, Cut, Treble, Bass, Middle and Volume controls, giving you plenty of scope to fine-tune your tone. Independent Top Boost switches: Access classic AC-inspired voicings at the flick of a switch. Top Boost mode adds extra gain, chime and harmonic complexity, while Normal mode delivers punchy cleans with plenty of body. Assignable spring reverb: Built-in convolution spring reverb with dedicated Level and Dwell controls lets you add everything from subtle ambience to spacious vintage depth, independently on each channel. Stereo tremolo onboard: Add classic pulsating movement or wide stereo textures, complete with independent channel assignment and dedicated Depth and Speed controls. Stereo series FX loop: Perfect for integrating modulation, delay and reverb pedals into your rig. The …

A preamp brings an instrument signal to a controlled level and shapes its impedance, gain and frequency balance before amplification or recording. A DI converts the signal for a balanced, low-impedance connection and may include ground lift, pad and transformer isolation. Combined units can add drive, cabinet filtering, effects loops and parallel outputs while keeping the direct path stable.

Stereo
Processes, creates or passes two audio channels. True stereo preserves separate left and right inputs, while mono-to-stereo effects generate spatial differences internally; routing, phase behaviour and whether trails remain stereo determine the resulting image. Some outputs sum to mono when only one socket is connected, which can change level or modulation depth.
