4. Stock / Variable Tremolo Switch:
The inner tremolo knob also serves as an On-On push-button switch. Pushing
the switch will toggle between variable rate mode and a fixed rate matching that
of the classic Wurlitzer models.
5. Speaker Cut:
This slide switch found on the amplifier PCB (S1) will effectively mute the
Speaker / Headphone output signal. This can be useful during some recording
and live performance situations.
* If no connection between speakers or a headphone jack are made to the
amplifier this switch should be set to the Off position.
6. Level Adjust Trim:
This trimmer, located on the amplifier PCB (VR3), sets the overall signal level
available at the Master Volume control. It should be adjusted so that, when the
Master Volume is set fully clockwise, playing at hardest dynamics does not
produce distortion from the speakers.
