The Blackstar HT-20R MkIII Combo is the latest version of Blackstar’s original groundbreaking 20 watt valve amp. The HT20R is defined by twin EL84 power valves which produce lush tone spanning pure boutique cleans through to mild overdrive and saturated distortion. Power reduction to 2 watts means its equally happy on stage or in your back room.

The Blackstar HT-20R MkIII Combo is now available from Merchant City Music, online and in our Glasgow store. Our friendly and knowledgeable staff are always happy to run you through its features, and set you up for a demo in our dedicated test booth. Alternatively, buy online for fast shipping to the UK, Europe and beyond.

EL84s are at the tonal heart of the HT-20R MkIII combo. Blackstar have used their 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.

For at home or in the studio the Power Reduction switch takes you down to 2 Watts without any compromise in tone: perfect for driving the EL84 power stage.

Simple and intuitive controls, combined with pro features like Blackstar’s patented ISF control, studio quality reverb, effects loop, XLR D.I. out and USB-C speaker emulated output, make them perfect for any performance situation – whether you’re in the studio, gigging in front of a small crowd, or playing to thousands.
