The Blackstar HT Studio 20 Head is a 2-channel 20-watt all valve combo has been designed for the recording guitarist. The Blackstar HT Studio features built in digital reverb and Blackstars patented and world renowned ISF tone control to get the best possible flexibility out of your amp.

HT Studio 20H

The Blackstar HT Studio 20 is the bigger brother of the HT-5, with the same fantastic features as the HT-5 plus a very nice and useable built in digital reverb section. 2x EL34 power amp valves and 2x ECC83 preamp valves power this amp, this is the classic combination first introduced in the '60's by Marshall amplification, only here Blackstar take the idea much further with the groundbreaking features such as the Infinite Shape Feature (ISF) which controls the characteristics of the power amp tubes, you can choose to use the amp to sound like an American amplifier, smooth and crisp or a British amplifier, hard hitting and powerful and everywhere in between. The HT Studio also incorporates an effects loop and a direct out for recording without the need to mic up. This head sounds great with pretty much any cab, though when combined with the Blackstar HTV-112 or HTV-212 you can really hear the tone that lurks inside these great amps.
