Blackstar HT-1

Blackstar went all out, packing tons of features in a 1 watt amp. The Blackstar HT-1 packs all the great tone and innovative features of the award-winning Blackstar HT-5R valve amp into a 1 Watt format. With just one watt it’s the lowest wattage amp of this low watt amp list.

But low on wattage doesn’t mean low on features. The patented ISF (Infinite Shape Feature) circuit gives you unique adjustment over the characteristics of the tone circuitry and takes you from the USA to the UK by adjusting where, in the frequency range, the middle scoop is located. This is a extremely innovative feature not seen anywhere else.

The HT-1 has a speaker emulated output that is great for recording. The controls, gain, volume and EQ (ISF) are simple yet allow a huge range of tones to be reproduced easily and at a very livable volume.

Blackstar has a full range of great tube amps and this 1 watt beast is no exception. It mixes classic guitar tones with cutting edge features to produce a responsive tube amp ideally suited to practice and recording.
