The HT Studio 20 is a highly versatile amplifier suited to a wide range of playingstyles and situations.
The Clean Channel provides a wide range of clean and moderately overdriventones. The voicing is typical of many ‘boutique’ style amplifiers with a ringing ClassA type performance. The overall character may be adjusted with the Tone controlfrom dark and warm through to bright and sparkling.
The HT Studio 20 Overdrive Channel is characterised by a tone which is 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,which also benefit the player in the way the overdrive cleans up beautifully as theguitar volume is reduced. Even at the most extreme settings, the Overdrive Channelremains natural sounding.
The HT Studio 20 Overdrive Channel also has its own highly flexible EQ sectionproviding a variety of overdriven tones. The patented ISF (Infinite Shape Feature)control is unique to Blackstar Amplification and represents a major step forward intone shaping flexibility. The ISF control shifts the response of the three control tonestack between a US type response at one end, and at the other a UK type response.Importantly, in between the two extremes lie an infinite number of alternative tonechoices that would be otherwise unavailable.
The HT Studio 20’s two channel design has been optimised for either preamp orpower amp overdrive, or a combination of both. The carefully voiced preamp andcathode biased dual EL34 power amp configuration provides the user with theability to create wonderfully lush valve tones. From mild overdrive that cleans up bybacking off the guitar volume control, to highly saturated distortion, this amp doesit all.
The HT Studio 20 also features a completely natural sounding digital reverb, whichis outstandingly musical on both clean and crunch tones and raises the benchmarkfor guitar amplifier specific reverb design.
