From the vendor
Tube Overdrive pedal. Friedman Brown Eye amplifier sound (BE Channel) in compact pedal format! Gain, Tone and Volume controls, a Fat toggle switch that adds lower frequencies, a Sat. toggle switch (Saturation mode). ECC83/12AX7 or 6Н2П-ЕВ tubes (2 pcs) 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. Also sold as a kit (back in stock soon).
