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 ZP2 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, and you’ll hear no change in tone.

Pickup blend control. Buffered inputs provide exacting control over blending the neck and bridge 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 counterclockwise brings in the neck pickup. The detent, or “click,” in the center 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 30 Hz. Turning the control clockwise boosts the bass. Turning the control counterclockwise cuts the bass. The detent, or “click,” in the center of the control is the “flat” position, zero boost or cut.

Midrange control. 15dB boost or cut of midrange at a center frequency of 330 Hz. On basses equipped with the ZP-2D, the midrange control is an internal trimmer on the circuit board. Turning the control clockwise boosts the mids. Turning the control counterclockwise cuts the mids. The midpoint in the control’s sweep is the “flat” position, zero boost or cut. (You will need to remove the control cavity’s cover plate to adjust this control.) On basses equipped with the ZP-2DM, the midrange control is a knob on the instrument’s face. Turning the control clockwise boosts the mids. Turning the control counterclockwise cuts the mids. A 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 of 3kHz. 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.
