Thanks to Owner-Manuals.com! This manual was exactly what I needed. As Amana was purchased by Maytag and later by Whirlpool, there was no way to receive it from their websites. I was lucky to find this resource.
A comprehensive Operating and Service Manual. All schematics are complete and easy to read. The PCB drawings and complete parts list are very helpful. I would definitely recommend this manual.

Creating �Custom� Wah Effects (Customize Mode) 7. With the TYPE knob, select the wah type on which you want to base your custom effect. * Until the TYPE knob is turned, the last wah type set to CUSTOM remains selected. TYPE knob CUSTOM (factory setting) ADVANCED BASS MIX CBY-WAH VO-WAH MO-WAH VOICE UNI-V Base wah type DOUBLE RESONANCE (p. 24) ADVANCED BASS MIX CBY-WAH VO-WAH MO-WAH * When selecting DOUBLE RESONANCE, first turn the TYPE knob to a setting other than CUSTOM, then select CUSTOM again. 8. Adjust the Q with the WAH RANGE knob. Q produces changes in the wah filter. The frequency range gets narrower as the knob is turned to the right (clockwise), creating a sharper filter with a tone with strong characteristics. Turning the knob to the left widens the frequency range, creating a less severe filter effect. When the knob is at the center position, the tone is as modeled. 9. Adjust the presence with the DRIVE knob (p. 25). The high-frequency components are attenuated more as the knob is turned to the left. There is no attenuation of the high frequencies when the knob is turned completely to the right.
