Description

The award-winning HT range is one of Blackstar’s cornerstone valve amp series. The HT MK III Series of guitar heads, combos and cabinets are the culmination of decades of design experience and innovation.

This 20W Head has two footswitchable channels & a built-in Reverb. Packed full of features, this head is a perfect choice for practice, recording and stunning tonal quality.

Key Features

  • Professional USB Recording Output – Now updated to USB-C, this is the simplest way to get valve tone onto your recordings.
  • Power Reduction Switch – HT-5 MK III and HT-20 MK IlI models feature a power reduction switch. In each case this will reduce the maximum power output to about 10% of the normal rated output.
  • Jam Along, Silent Practice & Record – Use the Line In for jamming along or listening to music, and the Line Out for ‘silent’ practice or recording.

Clean Channel

The MK III Clean channel is a very versatile and perfect for producing a wide range of classic clean and crunch tones. The two different voicings use both parts of an ECC83 valve exclusively for producing any valve compression or crunch.

Overdrive Channels

The overdrive channels give a rich, responsive Overdrive Channel with its own Voice switch. Choose between Classic Overdrive or  Modern Overdrive. The high-gain Voices are tight and focused.

Patented Infinite Shape Feature – ISF

The ISF control allows you to infinitely adjust the response of the tone control network between any of the traditional voicings in a way that has never before been possible. In this way you can design your own sound and truly find 'the sound in your head'.

Blackstar’s IR-based speaker simulation DSP software. Choose from 100s of microphone and cabinet combinations within Blackstar’s free software and store 3 CabRig presets directly into your amplifier.

Amp Cabinets

A speaker cabinet is responsible for turning your amplifier’s power into the sound you actually hear, and it plays a huge role in the overall feel and character of your tone. Different cabinet sizes, speaker types, and configurations can affect everything from low-end punch to clarity and projection. Cabinets can be open-back or closed-back, single or multi-speaker, each offering a distinct response and spread in a room. Whether paired with a powerful amp head or a compact setup, the right speaker cabinet helps define how your guitar sits in a mix and how it feels to play.

Amps

Guitar amps cover everything needed to amplify, shape, and project your guitar sound, from small practice setups to full stage and studio rigs. In this category you’ll find combo amps, separate amp heads and speaker cabinets, covering valve, solid-state, and hybrid designs, each offering a different feel and response. You’ll also see modelling and digital amps, built-in effects, footswitches, attenuation solutions, replacement speakers, valves, and essential accessories to keep an amp performing at its best. Whether you’re chasing pristine cleans, classic crunch, or modern high-gain tones, guitar amps and related gear are all about finding the right balance of power, tone, and control for the way you play.

Amp

An amp is an amplifier used to boost the signal from a guitar and shape its overall tone and volume. It plays a major role in how a guitar sounds, influencing everything from clean clarity to natural overdrive and distortion, and is a core part of any guitar setup for both practice and live performance.

Reverb

Reverb (short for reverberation) is an audio effect that simulates the natural reflections of sound in a physical space. When you play in a room, hall, or cathedral, the sound waves bounce off the walls, ceiling, and floor, creating a sense of depth and ambience. Reverb pedals and processors recreate this effect electronically, allowing guitarists and producers to shape how “big” or “live” their sound feels. From short, springy echoes that mimic vintage amp tanks to lush, atmospheric washes used in ambient or shoegaze music, reverb adds dimension and realism — turning a dry, flat tone into something immersive and expressive.
