Housing and appearance

The Blackstar HT Club 40 MkIII Amplifier is robustly built and impressively solid – just as it should be. The amp is finished in classic black, giving it a timeless and professional look. With its athletic shape, it is strongly reminiscent of traditional amps, but at the same time integrates modern elements. The control panel with its silver rotary knobs and the elegant Blackstar logo skilfully round off the look.

In terms of feel, the device is just as exemplary. The solid metal housing is impressive to the touch and emphasises the high-quality workmanship. In addition, the fabric covering in front of the speakers not only looks good, but also protects them from accidental damage. In short: with the HT Club 40 MkIII Amplifier, Blackstar has created a real eye-catcher that sets important design accents without unnecessary gimmicks.

Operating elements

The controls are intuitively arranged for user-friendly operation. The gain, volume, bass, middle, treble and ISF knobs can be used to precisely adjust the sound. The voice switch offers even more customisation options, while the reverb button provides an atmospheric echo. Additional features such as the booster or the effects loop round off the amplifier’s versatility.


A glance at the rear of the Blackstar HT Club 40 MKIII reveals that the amplifier is equipped with a large number of connections. In addition to the obligatory guitar input, there is a footswitch input for controlling the channel change and the booster and even a Recording Out connection for direct sound output during recording.

The Architecture Software

Blackstar’s own Architecture Software is another highlight of this amplifier. It makes it possible to make detailed changes to the sound profile and save them. Individual sound settings can be pre-programmed for different song parts or guitars. This gives the musician a high degree of flexibility and creativity.

Clean Channel

The amp’s clean channel impresses with a warm and round sound that is clear and defined at the same time. It provides a good basis for a wide range of musical styles – from jazz to country. The sound can be characteristically influenced using the ISF knob.

Overdrive Channel

The overdrive channel of the Blackstar HT Club 40 MkIII impresses with its enormous dynamics and rich gain reserve. From slightly saturated crunch sounds to biting high-gain riffs, this channel delivers enormous versatility. The booster also gives the sound more punch as required.

Recording Out

The Recording Out of the Blackstar HT Club 40 MkIII makes it easy to record the output. It makes it possible to record the sound of the amp directly and process it further without having to compromise on sound quality.


In conclusion, the Blackstar HT Club 40 MkIII is an impressive amplifier that combines outstanding sound quality, robust construction and user-friendly operation.
