Perfect for low-volume practice and recording, Blackstar’s HT-1R MK III is a single-watt combo amplifier packing tried-and-true tube-powered saturation. This 1 x 8-inch combo amplifier boasts both a pristine clean channel and a high-octane overdrive channel to run the gamut of 6-string tones, offering both a Voice control and an OD Select switch to tweak your tone. Sweetwater’s discerning tone chasers are thrilled by the HT-1R MK III’s versatile Overdrive channel controls, including Blackstar’s proprietary ISF control to sweep from classic American-style grit to high-gain British mayhem. Finally, the HT-1R MK III comes complete with a host of all-new enhancements, including cutting-edge CabRig DSP simulation and USB-C audio interface functionality, ensuring that the HT-1R MK III is just as capable in the studio as it is in the practice room.
The tube-powered Blackstar HT-1R MK III packs a massive spread of tones by virtue of its Blackstar's Infinite Shape Feature (ISF). When turned fully counterclockwise, you'll lend an American characteristic to your voice, with a tight bottom end and aggressive middle range. Turned all the way to the right, you'll enjoy more of a British vibe with a woodier sound that's less aggressive. However you dial in the HT-1R MK III, you'll enjoy a musical response that commands attention.


Thanks to the HT-1R MK III’s baked-in CabRig technology, you'll never need to mic a guitar speaker again. This state-of-the-art speaker simulation DSP allows you to choose from hundreds of microphone and cabinet combinations from within Blackstar's easy-to-use Architect software. You can then output straight to your computer-based recording setup via USB-C.
