Avalon VT 737SP Tube Channel Strip - Used
Mill River Music brings you a used Avalon VT 737SP Tube Channel Strip! We tested this rackmount channel strip and found everything to be in great working order; the knobs, buttons, lights and meters function wonderfully! Combining recording studio capabilities and putting things into one enclosure, the Avalon VT 737SP is a preamplifier, compressor, EQ and VU meter; taking up only two rack spaces, this unit gives you a precise idea of your audio going into your DAW!
