About the system
Volume control.
Unlike passive volume controls which decrease the
volume by shorting some of the signal to ground, causing degradation
in tone, the active volume control on the ZP3 allows the volume to be
set to any level without overall loss of highs or tonal change. Play a
note, let it ring while slowly turning this control up and down, you’ll hear
no change in tone.
Pickup blend control.
Buffered inputs provide exacting control over
blending the neck and bridge magnetic pickups. This feature allows
even the most subtle blend, for a greater variety of tone. Turning the
control clockwise brings in the bridge pickup. Turning the control coun-
terclockwise brings in the neck pickup. The detent, or “click,” in the cen-
ter of the control is the point where both pickups are on equally.
Bass control.
15dB boost or cut of bass at a center frequency of 30Hz.
Turning the control clockwise boosts the bass. Turning the control coun-
terclockwise cuts the bass. The detent, or “click,” in the center of the
control is the “flat” position, zero boost or cut.
Treble control.
15dB boost or cut of treble at a center frequency deter-
mined by the switch selection. Turning the control clockwise boosts the
treble. Turning the control counterclockwise cuts the treble. The detent,
or “click,” in the center of the control is the “flat” position, zero boost or
cut.
Piezo blend control.
Provides the ability to continuously blend the sig-
nal from piezo bridge and the magnetic pickups. Turning the control
clockwise alters the balance between piezo and magnetic pickups by
emphasizing the magnetic signal while de-emphasizing the piezo.
Turning the control counterclockwise de-emphasizes the magnetic pick-
ups while emphasizing the piezo.
