The HT-1 is Blackstar's 1-watt valve amp of 2010, a home and studio version of the HT-5. One ECC83 preamp valve with a clean/overdrive switch, gain, volume and Blackstar's ISF tone control feeds an unusual power stage: an ECC82 dual triode running push-pull for 1 watt, so it breaks up like a big amp at whisper volume. A speaker-emulated output serves headphones and recording, and the HT-1R adds digital reverb.
