Valve - 12AU7 Warm Boost Pedal

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) have marginal performance due to excess grid current at such low bias. This new design solves those issues, breathing new life into the tube, achieving full bandwidth and low-noise performance, all while maintaining that gooey non-linear tube goodness. This pedal will fatten up your tone like nothing else. Destined to be your always-on pedal. Basically, it is like an amp-in-box, taking you from warm clean tones up to compressed edge of breakup.  New for 2025 is an added DRIVE control that allows you to choose the amount of added warmth to your tone. Turn it down for neutral cleans, up for gooey tubeyness. Note the built in compression characteristic, super useful on bass!
