    For the guitarist searching for that classic British tone, look no further than Tone King’s Royalist MKIII all-tube amp head. With a hearty 40 watts of power from two channels, this amp will provide the style and sound to help you make your rock dreams come true. Taking inspiration from the original Royalist – one of Tone King’s most beloved amps – and revamping it with all the classic British goodness, you can now enjoy a range of great tones from sweet singing JTM45 vibes to punchy “Plexi” sounds and raging “Superlead” howls. Whether you crave crystalline cleans or cutting leads, this amp has got you covered. Get ready to experience old school British tones like never before with Tone King's Royalist MKIII All-Tube Amp Head!

    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.

    • 40W All-Tube Head
    • Two Channels with Volume Control and PULL FAT feature.
    • Three-Position 1964, 1967 and 1970 Voicing Switch, Per Channel
    • 6-Step Iron Man II Attenuator, Per Channel
    • Wide Variety of Vintage British Tone
    • Reactive load technology maintains the feel and response of your guitar amplifier.
    • High frequency switch to correct for an overly bright amplifier.
    • 1/4-inch Line level output

    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.

    Iron Man II Attenuator Per Channel

    The Royalist MKIII is a non-master volume amp, and when pushed into distortion at full  output power, delivers the complex harmonic spectrum which can only be obtained from a precise mix of preamp overdrive and power tube distortion. This combination is the key to the authentic tone and feel of a vintage British amplifier. In the past, creating this sound authentically required floor-shaking output volumes. The Royalist MKIII solves this problem by including two of Tone King’s legendary IRON MAN attenuators – one for each channel.

    The Iron Man II attenuators feature a tuned reactive load and special compensation circuitry that preserves the natural sound and feel of the amplifier. The result is a much more transparent attenuation versus a conventional attenuator, allowing the amplifier’s output tubes to run at full output power while delivering only a selected fraction of that power to the speaker.

    Using a complex tuned reactive load circuit, the Iron Man II simulates the frequency dependent impedance curve of a real speaker, avoiding a common pitfall found in most attenuators – a muffled, muddied sound lacking in presence and dynamics.

    Proprietary circuitry compensates for the differences normally found in low volume tone versus high volume. The result is a very natural sounding attenuation producing deep, rich tones with presence, at even the lowest settings.

    The two position HF switch lowers the high frequencies and gently emphasizes the midrange, which can help soften the cut of a single coil pickup or add extra mid push to the sound.

    Line Out

    A 1/4" unbalanced line out jack is provided on the back panel of the amp, with an associated level control. The line out can be used to drive any line level input, such as a recording device or mixing console.
