The Model 583E is a 500 series tube preamp with an EQ section that can function independently as two separate modules. Incredible on microphone source, it also features a Hi-Z input for instruments.

TrueTube delivers 250V to the tube, properly powering it so that it operates at its full potential and is not starved for power.
