Product Information

‘HT’ stands for ‘High Tension’ and refers to the high voltages used in valve circuits like HT MK III. The HT name goes back to the very beginning of Blackstar and its first products: the HT valve pedals.

EL84s are at the tonal heart of the HT-20RH MK III combo and head. Blackstark has used decades of valve amp design experience to combine the response and character of this classic British valve with a carefully voiced preamp to create wonderfully lush valve tones. From pure boutique cleans, to mild overdrive that cleans up by backing off the guitar volume control, right up to saturated distortion, this amp does it all.

The HT-20RH MK III comes equipped with a power reduction feature taking you down to 2W without any tonal compromise, perfect for driving those EL84’s hard at manageable volumes in the studio or home.

When you’re ready to take to the stage, switch to full 20W and utilise the XLR DI output to simultaneously feed direct to the sound engineer with incredible sounding cabinet simulation via CabRig™ IR-based speaker simulator software. CabRig™, the class-leading IR-based speaker simulator comes as standard in the HT-20RH 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.

From chiming ‘boutique’ cleans, to on the edge crunch, or full-on distortion, HT-20 MK III deliver ‘the sound in your head’.
