From the vendor
Single-channel tube preamplifier for bass guitar. Excellent clean sound in the best traditions of Alembic F2b and Trace Elliot V-Type. The preamp has a serial effects loop. Three-band EQ with additional switches (Mids, Bright and Deep) allows you to get a wide palette of clean and slightly overdriven tones. Preamp outputs: standard unbalanced, as well as balanced XLR. ECC83/12AX7 or 6Н2П-ЕВ tubes (2 pcs) are used. 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 100 x 100 mm. Enclosure type: Hammond 1590XX.
