The HT-DRIVE guitar pedal has dual cascaded, high voltage, triode stages which deliver gain from warm boost to screaming valve saturation. The unique 'A-Class' 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.
