Get the signature funky sound

The HoRNet WahWah is a digital replica of a vintage effect from the 70s made famous by guitarist and keyboard players around the world. This pedal represent a real signature sound for funky music and is an essential tool in every guitar player setup.

The effect is created using a resonant band pass filter, the pedal changes the frequency of the resonance and creates the typical “wah” sound. Due to the simplistic design of the circuit the Q of the filter and its gain is not constant and both get gentler when the pedal is completely pressed down, also the filter resonance is obtained through a feedback in the simple transistor amplifier and creates different level of distortion at different filter frequencies, this gives the effect a distinct sound that can’t be achieved with modern designs (and in fact after many years this kind of wah effect is still one of the favorite of many musicians).

We faithfully recreated the sound of the pedal starting from the analysis of the circuit diagram, then simulated it and measured the response. After having created a very good sounding wah effect by itself we added an envelope follower that will let you modulate the “wah” sound with attack and release set independently so you will be able to have a sort of “auto wah”. The modulation happens relatively to the current pedal position so you can get many different kind of sound, from the mid low “woh” to the screaming high “wah”, of course you can set the modulation level from “none” to “full”. As with any of the HoRNet Plugins the analog saturation given by the internal transistor amplifier can be turned of if you want a cleaner sound (but you probably won’t since it’s really cool and an important part of the effect sound)


The demo is fully functional except for the fact that every now and then it will silence out, you cannot save parameter values with your session and the plugin will not respond to automation coming from the host.


  • Classic wah-wah effect emulation
  • Analog saturation
  • Auto wah with attack and release
  • Auto output compensation
  • Midi controlled action
  • Midi learn
  • macOS (10.11 and later) and Windows support.
  • Apple Silicon native support (except for AAX)
  • 64-bit only on both on Mac and Windows.
  • Audio Units VST2.4, VST3 and AAX format.

Copy protection

The HoRNet WahWah has no copy protection, I don’t believe in copy protection, they are always cracked and they are annoying for the users, we all know you are not going to give away the plugin on the internet…

So simply download the plugin and enjoy your recordings!

Great wah pedal VST for a nice price. Works just fine with my stock FCB1010 in Reaper!

Jon Stewart says:

I love the pedal – great sound. I just wish that there was a way to use MIDI to turn it on and off. Then it would be perfect with my FCB 1010 pedal board.

Simon Jones says:

I love this plugin !!!

It sounds exactly like my old wah wah pedal. Also if you stick it halfway you get a perfect 1970's Bowie guitar sound.

Plus, I had a problem as I'd updated to Mac OS Catalina and the guys at hornet kept working with me to get it working.

Great Product !

Great Customer Service !

Used this on my newest album. I program all my metal, and I don't use the most advanced guitar library. This is wonderful for giving leads and solos more than a little life. My face always lights up when I draw the curves. It's like sprinkling magic on everything. All I need now is a foot pedal to control it. Jeez, at this rate, I'm going to turn into digital Kirk Hammett.

Tacerto says:

This is a cool sounding little unit. You won't be using it very often but when you need it, it will be there. For the price, it is a must have, even using it only once a year or so.

Silvio Mechow says:

Man, this is a fantastic Plugin! Sounds great and the price is a steal! Big thanx from Germany, love it …

Ricky Scott says:

I really wanted a good sounding wah plugin (and boy does it sound good) with full midi controllability and was thrilled when HoRNet turned my suggestion to reality. This sounds great on anything, drums, vox, guitar (obviously), synth. What a ridiculously cheap price for such a quality product too. Essential purchase.

Sergey Shkatov says:

Can't believe my ears! Sounds like a real analog wah!!!! Thank you! Cheers from Russia!

Matthias N. says:

This is exactly what i was looking for! A simple, good sounding wahwah plugin to experiment with on all kinds of sounds. Keep up the good work, i love what you're doing. Making good Plugins for an even better price.
Cheers from Germany!
