Top 5 Wah VST Plugins You Can Get (Paid & FREE Wahwah FX) |

If you want to give a vocal effect to your instruments, go no further. This article will show you the Top 5 Wah VST Plugins in 2023, both paid and free.

You’ve recorded a guitar part or some other part, and you feel it would be cool to add a wah wah effect to it. The good news is that you don’t even need to fiddle with actual pedals, as you can achieve this virtually right in your DAW.

These days there are enough plugins that emulate this effect, and we’ll talk about them below. But first, let’s understand what a wah pedal is?

What do wah wah pedals do?

Wah pedals create a peak that slides across the frequency spectrum from the lows to the highs. It produces an effect similar to vowel changes in the human voice that no other instrument has. As a result, when using a wah pedal, the musician can give movement to his sound, making it less static and more exciting and expressive.

A similar effect was first used in the early twentieth century by trombonists and trumpet players, who realized that they could get a somewhat “weepy” sound by closing and opening the front of their instrument with their hands.

Then, in the 1960s, engineers created the first wah pedals to give this sound to guitars. One of the most famous pioneers of this effect was Jimmi Hendrix.

The first wah pedals were pretty simplethey had only one button and a platform for the foot, so it was possible to glide. Then engineers began to add additional settings to them, like selecting a specific frequency and depth. There were also a lot of digital pedals that could work automatically.

These days, the most famous genres that use wah pedals are funk, rock, and metal. For example, this effect is often used on rhythm guitars in funk. As for rock and metal, musicians here often apply it to solo parts to highlight individual notes and give more emotion to their playing.

Besides guitars, the wah effect is actively used on bass, keys, and other instruments.
