Product Description for the Blackstar Venue Series HT Studio 20 Combo

The HT Studio 20 combo from the Venue series is the big brother of Blackstar's critically acclaimed HT-5, and offers huge versatility for home, rehearsal or studio use. Coupled with a cathode-biased EL34 power amp, the carefully voiced preamp provides the user with the ability to create wonderfully lush tube tones through the 12" Celestion speaker.

The Clean Channel on the Blackstar tube amp provides a wide range of clean and moderately overdriven tones. The voicing is typical of many 'boutique' style amplifiers with a ringing Class A type performance. The overall character may be adjusted with the Tone control from dark and warm through to bright and sparkling.

The HT Studio 20 Overdrive Channel is characterized by a tone that's high in gain, but lacks any of the detached top-end 'fizz' often found in many similar designs. This is a result of unique preamplifier and power amplifier shaping techniques. The overdrive cleans up beautifully as the guitar volume is reduced, so even at the most extreme settings, the Overdrive Channel remains natural sounding.

The HT Studio 20 Overdrive Channel also has its own highly flexible EQ section providing a variety of overdriven tones. Blackstar's ISF (Infinite Shape Feature) control represents a major step forward in tone-shaping flexibility. The ISF control shifts the response of the three-control tone stack between a U.S.-type response at one end, and at the other a U.K.-type response. Between these two extremes lies an infinite number of alternative tone choices that would be otherwise unavailable.

The HT Studio 20's two-channel design has been optimized for either preamp or power amp overdrive, or a combination of both. The carefully voiced preamp and cathode-biased dual EL34 power amp configuration provides the user with the ability to create wonderfully lush tube tones. From mild overdrive, that cleans up by backing off the guitar volume control, to highly saturated distortion, this amp does it all.

The HT Studio 20 also features a completely natural sounding digital reverb, which is outstandingly musical on both clean and crunch tones and raises the benchmark for guitar amplifier specific reverb design.

Best of both worlds.
Review by Manny
It\'s pretty rare to find an amp with such a lush, clear clean channel and so much distortion on tap on the OD channel! It\'s pretty incredible. I can only describe the overdrive channel as ballsy. It never gets \"heavy\" but rather distorts in a very natural way not found in most high-gain amps (you know what I mean, that over-compressed, fizzy top-end sort of sound? Ew). The ISF control is an awesome feature that either adds or cuts mid-frequency body to your tone. Cutting it (knob to the left) \"scoops\" the tone and gives the amp a drier, more percussive American sort of character. Boosting it (knob to the right) gives you a fuller Marshall-esque British tone. I keep it at about 2 o\'clock for a nice in-between sort of character. It really is so much more than just a regular \"presence\" knob. The HT 20 is just a super versatile amp. At any price, this amp rips. At THIS price? It\'s a must have. (Posted on 10/13/11)
