German engineered vacuum tube modeling preamplifier. The hand-selected 12AX7 vacuum tube creates a vintage flavor in your microphone, guitar, or bass. Great for recordings or live gigs. The warm sounds of a tube cannot be beat and add a whole new dimension to any sound. This preamp features 20db pad, 48V phantom power, Low Cut filter, and phase reverse. It is also equipped with a standard gain knob and output knob (chicken-head style!) The preamp mode selector allows you to set the best flavor for vocals, keys, bass, and more. Gain meter lights help you see exactly how strong your signal is and prevent clipping. Input and output jacks for both XLR and 1/4" jacks. Gently used, in excellent condition. 9 volt power supply not included.
