HT-20R MkII Guitar Amps

From chiming ‘boutique’ cleans, to on-the-edge crunch, or full-on distortion, the HT-20R MkII delivers ‘the sound in your head.’

EL84s are at the tonal heart of the HT-20R MkII combo and head. Decades of valve amp design experience have been combined 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.

For home or studio use, the Power Reduction switch takes you down to 2 Watts without compromising tone—perfect for driving the EL84 power stage.

With simple and intuitive controls and pro features like:

• Patented ISF control
• Studio quality reverb
• Effects loop
• XLR D.I. out
• USB speaker-emulated output

The HT-20R MkII is ideal for any performance situation—whether in the studio, gigging in front of a small crowd, or playing to thousands.

Enhanced Cleans

The HT-20R MkII offers two footswitchable Clean Voices:

• Voice 1: Bright and tight tone with solid bass response. The tone shaping is positioned early in the gain structure for a refined American tone and response.
• Voice 2: Highly responsive “chime” with a looser, resonant bottom-end for a British tone. Can be pushed into a mid-range overdrive when driven hard.

Enhanced Overdrives

The two footswitchable Overdrive Voices are high-gain tones without the detached top-end “fizz” often found in other designs:

• Voice 1: Classic “British” Blackstar overdrive. Rich and natural, it goes all the way to Super Crunch gain but cleans up beautifully.
• Voice 2: Inspired by the critically acclaimed HT Venue MkII high gain sounds, this overdrive adds aggression in the high-end with a tight, resonant low-end.

Patented ISF (Infinite Shape Feature) Tone Shaping

The ISF control allows infinite adjustment of the tone control network between traditional voicings, letting you design your own sound and truly find ‘the sound in your head.’

Professional Recording Connectivity

• USB output for the simplest way to get valve tone into your recordings.
• Pro balanced XLR D.I. output for speaker-emulated signals to connect to external devices for practicing, recording, or live use.

Power Reduction

Inspired by the patented Dynamic Power Reduction circuit, the Power Reduction switch lets you drop to 2 Watts at the push of a button without any loss of tone. Perfect for driving the EL84 power stage hard at lower volumes.

Reverb

The new studio-quality reverb is designed to perfectly complement guitar tones.

Unique Tilt-Back Design Head

The compact cabinet features:

• A 3-degree angle on the front face
• Top-loader panel
• Stage-friendly chickenhead knobs

This gives the HT-20R MkII a stunning boutique style. The head tilts back slightly, making it easy to dial in your tone.
