Input-1 and 2
The PZ-Pre features two ¼” inputs located on the right side panel.
The exible dual input design lets a player connect and switch
between instruments simply by stomping on the TOGGLE footswitch.
Most performers, whether they play acoustic guitar or mandolin, tend
to have two instruments on stage. The second instrument is often
for backup should a string break; in some cases, it may be tuned
differently, or it may even be a completely different instrument! The
PZ-Pre is equipped to be a control center for two instruments.

LEVEL-1 and 2
Both inputs are equipped with LEVEL
controls that let you adjust the volume
of each instrument. These controls
are used to compensate for the
differences in output level some
pickups produce. Once adjusted,
you can seamlessly switch between
instruments.
PZB-1 and 2 Piezo Pickup Buffers
Each PZ-Pre input features a special piezoelectric pickup (piezo)
buffer called the PZB that can be switched into the signal path
when needed. The PZB allows a passive piezo pickup to be
connected directly to the PZ-Pre without the use of a separate
preamp. The PZB increases the gain while elevating the input
impedance to 10meg Ohms. This ensures that the piezo pickup
'sees' the optimum input impedance for signal transfer which will
result in better tone. To
activate the PZB, use
a small screwdriver to
push in the recessed
switch. There is a
separate PZB switch
for each input channel.
