From the vendor
Single-channel tube guitar preamp. Two operating modes: Normal and Overdrive. In the Normal mode, the sound varies from clean to bluesy crunch, and in the Overdrive mode, you can get a palette of sounds from rock overdrive to high gain. For each mode, you can adjust the volume level. The Gain knob affects both preamp operating modes. Three-band EQ. ECC83/12AX7 or 6Н2П-ЕВ tubes (2 pcs) are used. Output MOSFET buffer. 6Н2П-ЕВ/12AX7 switchable heater via jumpers on the tube board. 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 1590BB.
