Yesterday @3volved on Twitter mentioned he recently picked up a Blackstar HT-Boost and was loving it. I’ve mentioned a few other Blackstar pedals, but not the HT-Boost, so thought I’d take a closer look. The HT-Boost, is a high voltage pedal (using 300V) which simulates adding two extra tube stages. Interesting.
Here is the official description:
The HT-BOOST Guitar Pedal’s high voltage gain circuit is like adding two extra hot tube stages to your amp so, unlike with inferior battery powered products, you don’t lose any precious dynamics or tone. Add to this an all-tube cut and boost tone section and a high level output which is specially designed to drive your tube amp hard and it all adds up to the ultimate boost pedal available.
The HT Range of tube overdrive pedals features true high voltage (300V) circuitry and are packed with innovations and tone. The revolutionary, patent-applied-for tone shaping feature ISF (Infinite Shape Feature) will redefine the tonal expectations of guitarists.
Add to this the no compromise speaker emulated output and you have the most cost effective way of getting real tube tones direct to disk or tape.
So whether you’re playing live or recording, with the HT Range of effect pedals by Blackstar you can finally get ‘the sound in your head’.
PURE TUBE BOOST

Two separate outputs provide one level for guitar pedals and an extra dynamic high level for tube amps. High integrity bypass for silent switching and driving long cables.
