EL84 Power Stage
EL84s are at the tonal heart of the HT-20R MK III combo and head. Blackstar 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.
From chiming 'boutique' cleans, to on the edge crunch, or full-on distortion, HT-20 MK III deliver 'the sound in your head'

The HT-20R 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 utilize the XLR DI output to simultaneously feed direct to the sound engineer with incredible sounding cabinet simulation via Blackstar's CabRig IR-based speaker simulator software.

Perfect for Playing & Recording
Alongside providing capture-ready valve tones at any volume, the HT-20R 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.
