From the vendor

Two-channel guitar preamplifier. The amplification section uses technology to simulate the processes occurring in tube guitar amplifier. The preamp's Clean and Lead channels have Gain and Volume controls. The three-band EQ is common to both channels. There is an additional output for connecting to the clean channel of a guitar amplifier for use as an effect pedal. Power supply: battery 9 V or regulated mains adapter 9…12 VDC. The dimensions of the main PCB 83 x 77 mm. Enclosure type: Hammond 1590BB.
