Controls
Volume: For the cleanest signal, set the Volume knob as high as possible,
without causing distortion or feedback.
Blend: Move the Blend slider to change the balance between the pickup and
the microphone.
Bass: Boost here to add depth and weight to the sound of the guitar. Note that
this control only affects the pickup signal.
Contour EQ: Two sliders (Contour and Contour Frequency) make up this EQ.
The Contour Frequency slider lets you tune in on a specifi c range of sound that
you can boost or cut with the Contour slider.
T reble: Boost to cut through the mix. Cut to mellow and subdue the sound.
Note that this control only affects the pickup signal.
Notch: Tune the Notch fi lter to remove low-end feedback. Raise the Volume
until feedback occurs, then slowly turn the Notch to the right until the feedback
is eliminated.
Phase: Use the Phase switch to improve bass response at low volume and
suppress feedback at high volume. If feedback occurs, push the Phase switch. If
feedback recurs when you change your location, press the switch again.
