The Acousti-Q is the first affordable tube-based preamp/blender for acoustic instruments. The Acousti-Q is the perfect solution for acoustic musicians helping to bring their personal style and sound to new heights! The Acousti-Q gives you the choice to use a single (piezo pick-up) or dual (piezo pick-up and mini-internal microphones) source. With 2 sources, you can blend the signals to achieve the perfect mix. Guitars, woodwinds, basses, brass instruments, virtually any acoustic instrument can benefit from the warm tube sound of the Acousti-Q.

The Acousti-Q employs 2 dual-servo microphone preamplifiers with separate gain controls for input, a phase switch, a 12-volt phantom power supply to accommodate miniature, internal condenser microphones, a variable notch filter, and sweepable mid-band EQ, as well as low and high shelving EQ controls. The master output section gives you the ability to set 2 separate volumes, one for normal volume, and the other, a boost, for solo playing.
