From the vendor
A compact tube guitar preamp. Two channels: Blues ( Marshall 1959 Super Lead) and Rock (Marshall JCM800). Each channel has Gain control (the Blues channel has 2 gain controls – Normal and Hi-Treble), a Volume control and a three-band EQ. After the Volume controls, there is an additional gain stage, which allows you to achieve the effect of overloading the power amplifier (similar to reference tube amplifiers). The preamp output level is adjusted using the potentiometers labeled "Master". ECC83/12AX7 tubes (3 pcs) are used. 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 166 x 105 mm. Enclosure type: Hammond 1590DD.
