Get to know them!

The Blackstar HT Club 40 MK III sets a new standard for the company's popular HT Venue series. This 40-watt, 2-channel, 1 x 12-inch tube combo amplifier contains the full gamut of classic and modern tones, from squeaky clean to raucous overdriven textures. You get two selectable voices on each channel for added flexibility, and each channel boasts a dedicated EQ, which includes Blackstar's patented ISF on the overdrive channel. The HT Club 40 MK III's Celestion Seventy 80 speaker churns out classic British-tinged tones.You'll also appreciate the HT Club 40 MK III's switchable power reduction, which gives you transparent attenuation down to 10% of the amp's rated power, and a great-sounding digital reverb with two selectable voices. The HT Club 40 MK III comes with CabRig speaker simulation baked in, giving you access to hundreds of mic and cab combinations, plus a USB-C output for dead-simple recording. This tube-loaded beast also includes an effects loop for straightforward pedalboard integration. Updated boutique styling with vintage-style chicken head knobs and a premium metal logo plate gives the Blackstar HT Club 40 MK III a bold look to match its expanded feature set.

Two channels of tube-fueled might

No matter what tone you're aiming for, the HT Club 40 MK III's two channels can nail it. Its clean channel is one of the most flexible we've experienced here at Sweetwater. For starters, its 2-band EQ offers an incredible level of sonic sculpting. What's more, its Voice switch takes it from a high-headroom, American-style chime to a character-filled, Class A-esque warmth that can be pushed into breakup when driven hard. The HT Club 40 MK III's overdrive channel includes Volume and Gain controls, a 3-band EQ, and Blackstar's vaunted Infinite Shape Feature, which carries you from tight, American-style tones to wooly British-style tones and all points in between. The overdrive channel also includes a Voice switch, enabling you to toggle between classic drive and hot-rodded contemporary distortion.

Loads of top-level features

The Blackstar HT Club 40 MK III is replete with player-friendly features. A power reduction circuit provides you with solid, transparent attenuation down to 10% of this tube combo amplifier's rated power. The HT Club 40 MK III includes a built-in digital reverb with a Dark/Light switch for added sonic versatility. You also get an effects loop with a dedicated level switch for integrating your pedalboard and studio processors. The HT Club 40 MK III comes with a 2-way foot controller, or you can use an optional 5-way FS-14 foot controller (sold separately) for even more hands-free control over the amplifier's four footswitchable voices.

Cutting-edge cab sims onboard

Thanks to the HT Club 40 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 your CabRig signal on a 1/4-inch unbalanced or XLR balanced cable or straight to your computer-based recording setup via USB-C.
