Robert Keeley is one of the best Guitar pedal designers and modders in the music industry. The worlds biggest stars and producers use his pedal from Steve Vai to U2 'The Edge'.
The Keeley Neutrino Envelope Filter and Auto Wah pedal is an extremely versatile and easy to use envelope filter that is based on the classic funk auto wah sounds used throughout the years.

The pedal is completely touch sensitive and works directly on how you attack the strings.
So you get all the sounds from one compact pedal.

The pedal is made for universal application so not only do guitarist benefit from this design so does Bass players (Bootsy Collins and all those great Funkadelic bass sounds) and keyboard players will be able to have the perfect filter by simply adjusting the gain control.

Keeley Electronics tune each opto-coupler is to perfection, so the Keeley Neutrino is like finding a magical vintage unit with that perfect tone and lower noise.

The Keeley Neutrino gives you the entire classic, funk, auto-wah sounds that have been used over the years Keeley used the classic opto-coupler design for a rich and warm depth to the effect. Envelope filter sound is an effect triggered by your pick attack or strength. The harder you pick, the harder it wahs”. Sounds bubble up from a deep rounded warmth to a shining brilliance. Solo notes are individually expressive based on how hard you play.

The Neutrino Envelope Filter has a simple set of controls so you explore a wealth of tones with ease. There is a Gain control to set the input level to an appropriate strength so that you can trigger the effect with any type of pickups or instrument level. This control is critical. Pick an open string on your guitar and adjust this control until you hear the wah sound rise and fall. Set just right it sounds like a wah pedal rocking back and forth as you play a note.
The peak control is how "sharp" or "warm" the effect is. You can think of this a way to make your wah sounds really mellow or Really "quaky"!

The Filter Selector lets you choose between 3 types of filters to carve out different tones and timbers
The Range Switch adjusts what frequencies are being stressed HI or LO. Easily find your voicing.

A side-mounted Direction Switch allows you to control which direction the wah sound goes. Wah up, wah down.

The Neutrino Envelope Filter is designed to work with bass guitar and keyboards as well. Simply adjust the Gain to get it to trigger the way you want. Then, adjust the Peak control to set how much it "wahs".
