Mz2 - Microphone and Instrument Preamplifier
The Mz2 preamplifier is the first stage of Everest. Microphone
signals are first preamplified with a discrete transistor stage. Hi-Z
instrument signals enter the Mz2 though a high-voltage vacuum
tube. Next in line, a Jensen line level transformer isolates the
signal before the gain control and insert point. The secondary
tube or solid-state preamp allows even more flavor combinations.
