Tone King Royce Preamp is a two-channel, high-voltage tube preamp pedal powered by three 12AX7 tubes. It combines classic British AC-inspired character with modern routing, offering rich cleans, shimmering chords and touch-sensitive overdrive in a pedalboard-friendly format.
Two channels, two classic voices
Each channel offers Normal and Top Boost modes. Normal delivers a bold clean foundation with a full low end and warm highs. Top Boost adds gain, extra chime and harmonic complexity, covering edge-of-breakup rhythm sounds through expressive lead tones.
Tube response for direct rigs
The built-in Zero-Watt Power Amp uses one of the three tubes as a genuine phase inverter stage, bringing natural compression and responsive feel. Dual onboard IRONMAN attenuators control the signal level after this stage. Cabinet IR processing and power amp simulation support direct connection to a PA, recording interface, powered monitors or headphones.
Effects, IRs and MIDI
Onboard stereo reverb with spring character, stereo tremolo and a bypassable series effects loop with stereo return give you a flexible foundation for stage and studio. Three IR slots per channel are selectable from the pedal. SYNERGY Editor provides access to 20 included OwnHammer IRs, user IR management and deeper settings. Store up to 128 presets for recall using an external MIDI controller.
