Blackstar HT Studio 20H

Blackstar · amplifier

The Blackstar HT Studio 20H is a 20-watt EL34 tube guitar amplifier head with two channels — clean and overdrive — covering the full range from country clean through natural break-up to high-gain saturation. Blackstar's ISF control shifts the tone stack continuously between American and British tonal signatures. The clean channel delivers sparkle and body with solid bass and shimmering top end; the overdrive channel reaches high gain without the detached top-end fizz common in similar designs, and cleans up smoothly from the guitar's volume knob. The head format allows flexible cabinet pairing. At 20 watts it bridges studio and small-stage use.
