The Thunder Knob was an all-tube design that ran a 12AX7 vacuum tube at 250V to deliver lush tube tone with tons of headroom. The pedal takes a standard 9v DC power input and boosts it internally via LBA's custom low noise DC to DC voltage booster. Any standard 9v pedal adapter will work if it can output at least 350mA of current. One of the few features of this simplistic design is the Thunder switch. This switch toggles between "Normal" which is a mellow tone and a mild degree of distortion (think early stage of break up from a tube amp) and "Thunder," which offers increased distortion, treble, and volume. Plus, when "Thunder" is engaged the Lightning Boy logo lights up! The Thunder Knob offers very low noise, quiet true bypass switching, plenty of gain, and that special Lightning Boy sound.
