The 4 Best Auto Wah Pedals — Reviews 2019

Wahs are among the most practical and most used effects in almost any genre of music that features guitars. What we’re generally used to is a standard wah pedal, where you have to manually manipulate the expression pedal in order to cut off certain parts of the frequency range. However, there’s another form of war that’s getting more and more popular. Auto ways are a versatile piece of gear that largely automates the wah-wah effect. There is no expression pedal to be worried about.

Instead, the auto wah works as an envelope filter which cuts off parts of the frequency range based on the power of the attack.
