Blackstar HT Boost Pedal
The HT Range of award-winning valve overdrive pedals feature true high voltage (300V) circuitry and are packed with innovations and tone. The revolutionary, patented tone shaping ISF (Infinite Shape Feature) will redefine your tonal expectations.
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'.
The HT-BOOST's guitar pedal's high voltage gain circuit is like adding two extra hot valve stages to your amp. Unlike 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, specially designed to drive your valve amp hard, and you have the ultimate boost pedal.
- Genuine valve design
- Operates at 300V HT
- Cascaded valve gain stages
- Hotrod your valve amp
- Silent switching operation
- All-valve tone control circuit
- Pedals or ‘hot’ valve amplifier outputs
- High integrity buffered bypass
- Power supply included
The Boost knob controls the amount of gain boost that is applied to the guitar signal. At low levels, a boosted clean sound will be achieved and your amp will sound more dynamic and full. As the Boost control is increased the amplifier will start to overdrive and the resulting distortion will be rich in valve harmonics and compression.
CUT AND BOOST BASS
The tone circuit on the HT-BOOST is known as a ‘cut and boost’ circuit. As the name suggests this allows a range of frequencies to be reduced (i.e. cut) or increased (i.e. boosted). Turn the control towards the ‘-’ to cut the amount of bass, or towards the ‘+’ to increase the amount of bass. Importantly, when the control is set to ‘0’ the amount of bass is neither cut nor boosted.
This output is designed to be connected directly to the input of your all-valve amplifier and provides a level of output dynamics unavailable in any other booster. Always use a good quality screened guitar lead.
This output has a lower level output and is designed for connection to the input of other pedals or the input of a solid state, digital or hybrid amplifier. Always use a good quality screened guitar lead.
OPERATES AT 300V HT
The HT pedal operates on a 300V DC anode supply voltage (High Tension voltage). This is the same used in traditional valve amplifier design and means the circuit has the headroom associated with a true valve design and will 'clean up' accordingly. The pedal will exhibit the compression and distortion characteristics associated with a true valve design.
Many hours of research showed us that only soft switching and a buffered bypass signal will give absolutely silent switching in high gain applications.
