ART Dual MP Dual-Channel Tube Microphone Preamp - Used

Looking for warm, rich tube analog saturation and clear gain for your studio setup or live rack? The ART Dual MP delivers classic tube warmth across two independent channels, making it a versatile workhorse for vocals, acoustic instruments, dynamic/condenser mics, and line-level signals. Driven by 12AX7 vacuum tubes, it brings natural compression, harmonically rich depth, and smooth tone shaping to digital recording environments.

Condition is Very Good overall. The unit shows normal light cosmetic rack wear and minor surface scratches from careful studio use (see photos for full detail). Otherwise, it remains remarkably clean, fully functional, and ready to plug in and record.

Our technicians have thoroughly tested the unit, verified clean pot operation, tested switch responsiveness, and ensured all inputs, outputs, and vacuum tube circuits are functioning properly.
