From shimmering boutique cleans to biting crunch and full-on distortion, the HT-20 MK III delivers "the sound in your head"!

The HT-20R MK III elevates the acclaimed design of the award-winning MkII series to a new level with incredible power, stunning looks, and groundbreaking new features—from enhanced tones to the addition of IR-based CabRig speaker simulation software.

EL84 Power Stage

EL84 tubes are the tonal heart of the HT-20R MK III combos and heads. Blackstar has leveraged decades of experience in tube amp design to blend the response and character of this classic British tube with a carefully tuned preamp, creating wonderfully rich tube tones. From pure boutique cleans through mild overdrives that clean up by rolling back the guitar’s volume knob, to saturated distortion—this amp does it all.

Focused to Stage-Ready

The HT-20R MK III features a power reduction function that drops output to 2 watts without tonal compromise—perfect for pushing the EL84s hard in the studio or at home at manageable volumes.

When you’re ready to hit the stage, switch to full 20 watts and use the XLR DI output to send an incredibly realistic cabinet simulation directly to the sound engineer via the CabRig IR-based speaker simulation software.

Perfect for Playing and Recording

The HT-20R MK III not only delivers recording-ready tube tones at any volume but also includes a direct USB-C output that can send 2 channels (left and right) to your DAW, offering the easiest way to record authentic tube tones without an interface.

The best part? These amps have built-in load protection, meaning you can use them without a connected speaker cabinet for silent practice and recording.

IR-Based CabRig Speaker Simulator

CabRig, Blackstar’s industry-leading IR-based speaker simulator, comes standard in the HT-20R MK III, offering hundreds of different cabinet, microphone, and room combinations. Save your favorites in three presets for direct access from the amp. Get premium tube tones into your headphones, monitors, and mixes.
