The HT-DRIVE guitar pedal has dual cascaded, high voltage, triode stages which deliver gain from warm boost to screaming valve saturation. The unique 'Class A' tone control cuts the fizz without making your 'backed-off' tone sound dull and lifeless. Add to this a no-compromise speaker emulated output and you have the ultimate overdrive pedal. UNIQUE 'CLASS A' TONE CONTROL Our 'Class A' tone control was inspired by our research into the high frequency power amplifier response of Class A amps. Its unique design always retains your guitars natural character and ensures your 'backed off' tone is never dull and lifeless. SPEAKER EMULATED OUTPUT The Blackstar emulated output design is a new benchmark for pro direct recording. This no-compromise design makes it easy to get your tone to disk and tape. You can also use it to run a line out to a PA. 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. ISF CONTROL The ISF control works in conjunction with the Tone control. It allows you to choose the exact tone signature you prefer. Fully CCW is a more American characteristic with a tight bottom end and more aggressive middle, and fully CW is a British characteristic which is more ‘woody’ and less aggressive.
