Designed with the recording studio and gigging artist in mind, the Blackstar HT-20 Studio is a 2-channel 20-watt all valve combo has been designed for the recording guitarist. Built in digital reverb and ISF tone control offers tonal shape-shifting on the fly.

HT Studio 20

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.

One amp, multiple models

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. The 12 inch Celestion Seventy 80 speaker is crisp and detailed with a bright top end, combined with the amplifier section this makes for a very powerful package. A 3-band EQ section also means that you can make small changes in tone so that you can get a sound that is complimentary to your recording or performance environment.

Power, precision and versatility, the Blackstar HT Studio 20 1X12 Combo Amp Guitar Amplifier oozes personality and is ready to be your workhorse for many years.

She bites...
Posted on 06/06/2012 by Patrick The mid-range valve amp market brims with big names and all-time classic amplifiers. The Blackstar HT-20 fought Vox's AC15, Fender's Blues Junior and Orange's Tiny Terror to win herself a partnership with my Fender Lonestar Stratocaster, and for me, this amp wins every time.

Features wise, the Blackstar is fantastically simple and for me and my blues-orientated playing, provides all I need. Simple 3-band EQ is very responsive and the bass doesn't muddy the mid-range: an impressive feat at this price. In addition, an ISF knob is featured which shapes the tone towards tighter American-esque amplifiers or a sharper British sound. This unique feature is exceptionally useful and is incredibly diverse when used in careful conjunction with EQ. The two clean and overdrive channels are perfectly executed: the clean channel is precise and accurate, particularly when the amp's tone control is cranked up. With the master volume cranked up, this amplifier's generous four valves really come into their own, and the amplifier begins to develop character and diversity; biting when played aggressively yet drawing back for softer phrases. My one quibble is that I find that it takes the master volume around 2 o'clock (a level that I am rarely able to reach!) before the drive is suitably audible. The overdrive channel is again, amazingly diverse: at low gain settings, and with my guitar's volume control rolled back I get wonderful dynamic variation, especially without a plectrum. At higher gain settings, the tone is dirty but she really sings.

For me, this amp is all but perfect and thus fully deserving of the full five stars from me: an absolutely essential buy for anyone in the market for a valve amplifier that won't break the bank!
