The Zeta Sound Lady Dirt is a high voltage overdrive pedal based around two 12AX7:s. Three gain stages and a cathode follower driving a tone stack, tweaked with selected components. True bypass with shielded signal wiring. Knobs for Dirt, Treble, Mids, Bas and Volume. Powered by an external 1A, 12VDC, 2,5mm center positive adapter. Voltage is internally converted to 250VDC feeding the tubes. When powered up it waits about 30 sec until the high voltage is placed on the anodes.
