VALVE – 12AU7 Boost Pedal
3
Description
VALVE is an all-tube boost pedal (no silicon involved) operating in starved-plate and
starved-heater mode, which is difficult to pull off. Most attempts (Matsumi) fail due to
excess grid current at such low bias. This new design solves those issues, breathing life
into the tube, achieving full bandwidth and performance, all while maintaining that
gooey non-linear tube goodness. This pedal will warm up your tone like nothing else!
Waveforms show clean, but warm and harmonically rich response for single coils, with a
bit of hair added for humbuckers. Put a boost pedal in front of the VALVE for fantastic
tube overdrive, similar to a Butler!
