Tone King Royce Preamp Pedal

The Tone King Royce is an advanced two-channel, high-voltage tube preamp pedal powered by three 12AX7 tubes. It authentically recreates the classic British AC amplifier sound, delivering shimmering highs, rich harmonics and dynamic touch response. The built-in Zero-Watt Power Amp with phase inverter circuit provides natural tube compression, organic response and three-dimensional tone.

Each channel features independent Normal and Top Boost modes, along with comprehensive tone controls. Stereo reverb, stereo tremolo, built-in IR technology, MIDI control and versatile connectivity make the Royce an excellent choice for stage, studio and advanced pedalboard setups.
