The Blackstar HT-BOOST Valve Boost Effects Pedal's high voltage gain circuit is like adding two extra hot valve 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-valve cut and boost tone section and a high level output which is specially designed to drive your valve amp hard and it all adds up to the ultimate boost pedal available.

Pure Valve Boost

High voltage valve design for true valve dynamics and feel 100% all-valve gain just like adding two extra hot valve stages to your amp. Valve ‘cut&boost’ tone circuit for musical equalisation. Two separate outputs provide one level for pedals and an extra dynamic high level for valve amps. High integrity bypass for silent switching and driving long cables.

The HT Range of award-winning valve 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 valve tones direct to disk or tape.

So whether you’re playing live or recording, with the HT Range of pedals you can finally get ‘the sound in your head’.
