Wah Adjustment" The two components that control the wah are an LED and an LDR. On the CLW, PWA-II, PWV-II, PDW-II, and PBA-2 they are labeled L4 and LDR3. On the VAI-1, VAI-2 and MARK 1 they are marked L2 and LDR2. On the PWO and PWOV they are marked L3 and LDR3. Basically, those components are moved in relation to one another (and to the shutter opening) to achieve a desired setting. The more direct light from the LED hitting the face of the LDR, the higher the wah frequency. For a more mid rangy wah tone point the two components slightly away from one another.
Each time the components are moved the pedal should be sound tested. Make sure to turn the pedal over to shield out the room light. Otherwise the pedal will give a false reading due to the room lighting. Once you understand this basic maneuver you can experiment with different settings until satisfied.

“Secret” Wah Adjustment On the VAI-1, VAI-2, MARK 1, PWO and PWOV you can quickly and easily adjust the wah tone by tightening or loosening the nut that holds the inductor in place. The inductor is a round component (about the diameter of a quarter) located just below the output jack. Tightening or loosening the nut changes the tension on the wire windings and ultimately makes the wah brighter or more mid-ranged. You’ll notice a small amount of glue on the nut, don’t worry; this is a special glue that will stay on and hold the position of the nut.

NOTE: Just don’t tighten down on this nut with any real force or you may crack the ceramic housing. A small amount of tension can go a long way in terms of wah tone.
