Introducing the HT-1RH MK III

The HT-1RH MK III takes the revered design from the award-winning MkII series to new heights with incredible performance, gorgeous looks and game-changing new features from improved voicings to the addition of our IR-based CabRig™ speaker simulator software.

Tonal Options

The HT-1RH MK III has 2 channels, clean and overdrive, each with 2 voicing options. With HT-1RH MK III, each Voice switch introduces comprehensive circuit alterations in both the preamp and power amp to recreate authentic reference tones without compromise. This includes EQ voicing, tone stack position in the circuit, the gain, and power amp damping. Achieve diverse tonal options with the flick of a single switch!

Perfect for Playing & Recording

Alongside providing capture-ready valve tones at any volume, the HT-1RH MK III comes equipped with a direct USB-C output which can send 2 channels (left and right) to your DAW, ensuring the easiest way to capture authentic valve tone in recordings without the need for an interface.

The best part? These amps have in-built load protection, meaning you can use them without a cabinet connected for silent practice and recording.

IR-based CabRig™ speaker simulator

CabRig™, our class-leading IR-based speaker simulator comes as standard in the HT-1RH MK III, offering hundreds of different cabinet, mic, and room combinations. Save your favourites to three presets for easy access directly from the amplifier. Get premium valve tones into your headphones, monitors and mixes.
