The Valvedriver is a tube-based overdrive pedal designed for those who want to experiment with tubes without exposing themselves to high voltages. It is based on the BoobTube circuit and features an internal voltage multiplier. The difficulty level is intermediate and the amount of parts is moderate. All components are easy to get. The pedal is designed to use onboard potentiometers, making it tidy and compact. It is versatile, allowing you to build a clean tube version as well as an overdrive one. The controls include a Tone knob, which is a high-cut filter, a Volume knob to control the output volume, and a Gain knob to set the gain at your preference.
