At the core of the HT-20R MK III lies a pair of EL84 valves, delivering the unmistakable chime, warmth, and bite of classic British tone. Drawing on decades of Blackstar's valve amp design expertise, this amp pairs a finely tuned preamp with the dynamic response of EL84s to offer a wide tonal palette—from pristine boutique cleans to rich edge-of-breakup overdrive, and all the way to saturated high-gain distortion. It’s a true all-rounder.

The power reduction switch lets you drop from 20W to 2W, letting you push the power section for full valve saturation at more manageable volumes—perfect for studio sessions or late-night jams at home.

Ready for the stage? Crank it back up to 20W and use the XLR DI out, featuring CabRig™, Blackstar’s next-gen IR-based speaker simulation, to send stunningly realistic cab tones straight to the PA or mixing desk—no mic required.

For direct recording, the HT-20R MK III includes a USB-C output, sending a stereo signal straight to your DAW without the need for an interface. Whether you’re tracking in the studio or laying down demos at home, capturing authentic valve tone has never been easier.

And for silent practice or late-night sessions, the amp includes built-in load protection, so you can run it safely without a connected speaker, using headphones or monitors without compromise.
