All-tube boost pedal! A dream come true! :)

David5140, 22.07.2014
There are many boost pedals out there but this one is all-tube, not solid state.
I compared it with an other solid state boost pedal and I believe I could hear a significant difference. Of course, it's all-tube. There's no diode-clipping.
It's a high voltage pedal (which I read in reviews is better) and the foot switch is very smooth without hard mechanical clicking (everything helps!) and the tone controls, also, are all-tube (or valve).
The only 'complaints' I have is that it's buffered bypass not true bypass and the tone control knobs don't have a middle detent but these can be considered minor details. No big problems.
It also has a high and low output depending whether one connects it into a tube amp or into a solid-state amp or pedal respectively.
And it includes a power supply. So, one can plug and play immediately!
The looks and build are very good, too. And the tube lights up.
To conclude, I searched for a number of boost pedals and actually didn't find that many that are all-tube. Blackstar is a quality brand and that convinced me to buy this one and I don't regret it one bit.

Doping for the Valvestate!

17.07.2016
I use the Blackstar HT Boost to blow the preamp tube into my Marshall Valvestate VS65R, I usually do that with the Ibanez TS9 or the Boss SD1, but I wanted another gain stage with a real tube right in front of the amp and was more than positively surprised. While "normal" boosters in front of the amp add just a little more tug with minimal volume boost, the HT Booster adds a lot of pressure, along with nice tube sound, but without totally bending the amp's basic sound, just awesome!
My main rhythm rhythm is now out
TS9 -> HT Boost -> Amp.

With the controls you should not overdo it, the more boost, the more you should down the bass, but everyone has to decide for themselves.

The part is large, but well-made, the controls have a good resistance to rotation and can be switched off the booster without annoying crackling noise, rushing does nothing and the bypass is also ok.

I'm very happy with the booster, it enriched my sound, I can only recommend it, especially for those who want to seed a hybrid or a transenal!
