Unleash Your Best Tone with the Tone King Royalist MKIII 40-Watt Two-Channel All-Tube 1x12-Inch Guitar Combo Amplifier

The original Royalist was the first Tone King amp to offer the best elements of British tone and was one of the company’s most beloved amps. The new Royalist MKIII is a 40-watt, two-channel, all-tube, 1x12” combo that expands on that legacy by faithfully reproducing early British tones ranging from the sweet, singing JTM45,to the iconic “Plexi” sound, all the way to the raging “Super Lead”. The Royalist MKIII authentically captures the vintage nature of these iconic amplifiers, delivering tones that span from clean to edge-of-breakup, to the bright-crunchy leads found on countless classic rock tracks that helped shape music history. The built-in Iron Man II attenuator on each of the channels features a tuned reactive load and special compensation circuitry that allows the power tubes to be fully driven, yet only allowing a fraction of the volume through the speaker.

All-Tube Signal Path

The Royalist MKIII features an all-tube signal path with three 12AX7A preamp tubes and two EL34 power tubes. In addition to the output tubes, a 5AR4 rectifier tube delivers the authentic “sag” feel and response which is signature of classic British amps.

Independent Volume Controls with FAT Option

The Volume for both Channel A and Channel B features a PULL FAT option which changes the feel of the amplifier by delivering more low-end frequencies on the first gain stage of the preamp. The FAT setting is ideal for a clean sound with a bit of bottom end or to add some juice if you are running overdriven.

Independent 3-Way Voicing Switch Per Channel

The 1964, 1967 and 1970 three-position voicing switch on each channel allows you to choose the particular preamp, tone stack and negative feedback (power amp) from three of the most iconic vintage British amps.

1964

Delivers a balanced treble response, lower gain, and less aggressive attack inspired by a vintage JTM45 or Bluesbreaker.

1967

delivers the crisp treble response and aggressive attack of a vintage “Plexi”.

1970

This highest gain setting delivers the raging “Super Lead” sound.
