HT Boost

HT Boost Overview

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

Further Info

  • Boost Control

    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.

    High Output

    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.

    Low Output

    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.

    Silent Switching

    Many hours of research showed us that only soft switching and a buffered bypass signal will give absolutely silent switching in high gain applications.
