Blackstar HT-20 MkII 20W Combo Amp with EL84 Power Stage and Reverb (Surf Green, Refurbished)

From chiming cleans, to on-the-edge crunch, to full-on distortion, the Blackstar HT-20 MkII delivers ‘the sound in your head’. EL84s are at the tonal heart of the HT-20R MkII combo and head. Blackstar has applied decades of valve amp design experience to combine the response and character of this classic British valve with a carefully voiced preamp to create wonderfully lush valve tones. From pure boutique cleans to mild overdrive that cleans up by backing off the guitar volume control, right up to saturated distortion, this amp does it all. The HT-20R MkII comes equipped with a power reduction feature taking you down to 2W without any tonal compromise, perfect for driving those EL84’s hard at manageable volumes in the studio or home. When you’re ready to take to the stage, switch to full 20W and utilize the XLR DI output to simultaneously feed direct to the sound engineer with incredible sounding cabinet simulation. It is available in a Surf Green finish. This is a certified refurbished product backed by a 90-day warranty.
Professional Recording Connectivity
The HT-20R MkII comes equipped with a direct USB output for the simplest way to get valve tones into your recordings without the need for an interface. Also included is a fully specified stereo recording output via XLR and jack with selectable cabinet simulation options of 4×12 or 1×12. The best part is that these amps have built-in load protection, meaning you can use them without a cabinet connected for silent practice and recording.
Patented ISF
The patented ISF (Infinite Shape Feature) control is unique to Blackstar Amplification and represents a major step forward in tone-shaping flexibility. The ISF control shifts the response of the three-control tone stack between a US-type response at one end and a UK-type response at the other. Importantly, in between the two extremes lies an infinite number of alternative tone choices that would be otherwise unavailable.
Ground-Breaking Cleans
The HT-20R MkII has two footswitchable Clean Voices - Voice 1 which is a clean voice that gives a bright, tight tone with a solid bass response. The tone shaping is positioned early in the gain structure for a refined American tone and response. Voice 2 gives a highly responsive ‘chime’ with a looser, resonant bottom-end for a British tone that can be pushed into a mid-range overdrive when driven hard.
Richer, More Responsive Overdrives
The two footswitchable Overdrive Voices are characterized by a tone that is high in gain but avoids any of the detached top-end ‘fizz’ often found in other designs. Voice 1 is the Classic ‘British’ Blackstar overdrive. Rich and natural, it goes all the way to Super Crunch gain but cleans up beautifully. Voice 2 is inspired by the critically acclaimed HT Venue MkII high gain sounds, and this overdrive has additional aggression in the high-end with a tight and resonant low-end.
Stage Ready
Connect a two-button footswitch for full stage control over the HT-20R MkII’s channels and voice settings. FX loop and pro-XLR DI with inbuilt cabinet sims complete the stage-ready package.
Studio Quality Reverb
Blackstar’s new studio quality reverb has been referenced against the most revered vintage and modern reverb units, designed to perfectly complement guitar tones.
Unique Tilt-Back Design Head
The compact cabinet of the HT-20R MkII has a 3-degree angle on the front face, a top-loader panel, and stage-friendly chickenhead knobs giving the amp a stunning boutique style. The head tilts back slightly to make it easy to dial in your tone.
