From the vendor
Tube overdrive pedal, designed on the basis of the schematic circuit of the Soldano G.T.O. Added option to switch pre-gain tone correction (G.T.O./SLO), as well as option Boost. Three control knobs (Gain, Volume and Tone). The schematic is adapted for the use of 6Н2П-ЕВ vacuum tubes. ECC83/12AX7 tubes also can be used. 6Н2П-ЕВ/12AX7 switchable heater via jumpers on the tube board. True bypass (relay). Power supply: regulated mains adapter 12 VDC (load current of 1 A or more). To power the tube plates an internal DC-DC high voltage boost power converter is used (Nixie type). The dimensions of the main PCB 84 x 100 mm. Enclosure type: Hammond 1590BB2. Also sold as a kit (available soon).
