From the vendor

High-gain overdrive pedal. The sound of your favorite tube amp or preamp in pedal format. Three control knobs (Gain, Volume and Tone) and two switches (Boost and Structure) will allow you to get the desired tone. Two vacuum tube ECC83/12AX7 or 6Н2П-ЕВ are 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. The kit includes the PCBs and parts except for the vacuum tubes. Sold as a kit only.
