Blackstar HT-20RH MK III Head

The Blackstar HT-20RH MK III is a 20-watt all-tube guitar amplifier head that combines boutique-quality clean tones, modern high-gain overdrive and professional recording features in one compact and highly versatile package. Developed using technology from the acclaimed HT Venue MK III series, it delivers authentic valve tone for home practice, studio recording and live performance.

The amplifier is equipped with two ECC83 preamp valves and two EL84 power valves, providing exceptional dynamics, rich harmonic response and authentic valve compression. Two footswitchable channels, each with two selectable voices, offer everything from sparkling boutique cleans to aggressive modern distortion. The Clean channel features enhanced tone control, while the Overdrive channel includes Blackstar's patented Infinite Shape Feature (ISF) for continuously variable American-to-British tonal shaping.

The HT-20RH MK III features CabRig™, Blackstar's premium IR-based DSP speaker simulator. Players can select from hundreds of virtual cabinets, microphones, microphone positions and room environments, storing up to three presets directly inside the amplifier. A balanced XLR output, USB-C connectivity, stereo headphone output, 20 W / 2 W Power Reduction, effects loop with switchable operating level and digital reverb make the HT-20RH MK III an ideal solution for professional recording, silent practice and live performance.
