What is a Wah pedal

• Wikipedia

Preventing thump or pop when auto-engaging the Wah

• Cliff (answering a question about hearing a thump when auto-engaging a Wah): "The thump isn't the wah, it's the Input Impedance changing. If your preset is set to Auto for the Input Z, when you engage the wah the impedance switches. This causes a slight thump if you are playing since the load on your guitar changes. If you want to avoid this, turn Input Z to 1M OHM (Input Z is in the INPUT/GTE page of the Layout menu)." Source
• Cliff: "Set the Input-Z on the preset to 1M rather than Auto. The reason the Wah engages abruptly is because it switches the input impedance. Setting Input-Z to 1M overrides the impedance switch (and, frankly, sounds better IMO)." Source

Seek wah

• The random wah effect is also known as "seek wah", based on a Z.VEX pedal.

Tips

• Decreasing Max Freq makes a heavily distorted wah tone cut better through the mix.
• Use Auto Engage with Off Val set to 95% to switch off the wah automatically at toe down position.
