Features
The HT-1 is the perfect studio and practice amp, packing all the great tone and
innovative features of the award-winning HT-5 valve amp into a 1 Watt format. The
patented ISF (Infinite Shape Feature) circuit gives you infinite adjustment over the
characteristics of the tone control network and takes you from the USA to the UK
and anywhere in between. So now you can effectively design your own tone and
finally find ‘the sound in your head’.
In making the HT-1 ideally suited to home and studio use, the aim was to develop
a valve amp which sounded full and toneful even at the lowest volume level. With
this in mind the Blackstar design team designed a brand new valve power amplifier
topology. The HT-1 power amplifier is a low powered push-pull design which
produces the crunch and break-up characteristics of a traditional 100W output
stage but at a much lower volume. This is achieved by the use of an ECC82 dual
triode in push-pull configuration producing 1 Watt output, which is rich in valve
harmonics and compression.
The HT-1 also has a fully specified speaker emulated output which further enhances
the studio credentials and allows any guitarist to get amazing valve tone straight to
tape or disk, or through headphones.
Add to this an MP3 / Line Input, along with a 4-16Ω speaker output which allows
you to run the amp into an external speaker cabinet of your choice, and you have
everything you need for recording or practising.
