Input-1 and 2
The PZ-Pre features two ¼" inputs, each equipped with its
own LEVEL control. The fl 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.
PZB-1 and 2 Piezo Pickup Buffers
Each PZ-Pre input features
a special piezoelectric
pickup (piezo) buffer that
can be switched into the
signal path when needed.
These 100% Class-A
buffers allow a passive
piezo pickup element to
be connected directly to
the PZ-Pre without the use
Input-1
of a separate preamp. The
piezo buffer increases the
gain while elevating the
input impedance to 10meg ohms. This ensures the piezo pickup
"sees" the optimum input impedance for signal transfer which will
result in better tone. To activate the piezo buffer use a tweaker
(small screwdriver) to push in the recessed PZB switch. There is
a separate PZB switch for each input channel.
LEVEL-1 and 2
Separate level controls
adjust the volume of each
instrument input for the
proper on-stage balance.

Tuner Output
This buffered output is dedicated
for an electronic tuner. Since it is
buffered, connecting a tuner won't
load down your pickup's tone. The
TUNER output is always on to allow
silent tuning in conjunction with the
MUTE footswitch.
Mute Footswitch with LED
The MUTE footswitch allows silent
tuning on stage through the TUNER
output and may also be used for
instrument change-over. Depressing
this footswitch will mute all outputs
except the TUNER out. The LED
illuminates to indicate the PZ-Pre
is in mute mode.
Blend-Mix
The BLEND-MIX function is typically used with instruments that
have two pickup elements or two different pickup systems. It
allows you to blend the two input channels using the LEVEL
controls to set up a mix. For instance, you can use the MIX mode
to blend an active on-board pickup with a passive piezo to create
a more natural acoustic sound. Alternatively, you can use the MIX
mode to connect two guitars to one amp for jamming with another
player. The MIX mode is activated by depressing the recessed
BLEND-MIX switch using a small screwdriver or tweaker. The
TOGGLE footswitch will not work when the MIX mode is active.
Input-1 is specially equipped to allow a stereo TRS cable (Tip,
Ring, and Sleeve) to access both PZ-Pre channels. This feature
is designed for instruments that combine two pickup systems
through a stereo TRS jack. A stereo TRS cable will allow you
to connect both pickups to separate PZ-Pre inputs with a single
cable. From there you can toggle between the two pickup systems
or blend them together.
