Blackstar HT-20R MK III Combo

The Blackstar HT-20R MK III Combo is a 20-watt all-tube guitar combo amplifier that combines boutique-quality clean tones, modern high-gain overdrive and professional recording features in one versatile package. Based on the acclaimed HT Venue MK III platform, it is designed for guitarists who demand authentic valve tone at home, in the studio and on stage.

The amplifier features two ECC83 preamp valves, two EL84 power valves, and a 12-inch speaker, delivering exceptional dynamics, touch sensitivity and full-range tone. Two footswitchable channels, each with two selectable voices, provide everything from sparkling boutique cleans to aggressive high-gain 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-20R MK III is equipped with CabRig™, Blackstar's premium IR-based DSP speaker simulator. Choose from hundreds of cabinet, microphone, microphone position and room combinations, 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 this an ideal amplifier for live performance, recording and silent practice.
