EL84s are at the tonal heart of the HT-20R MK III combo and head. Blackstar 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’
