OVERVIEW

Dynamic wah sound which is an effect based on your pick attack or strength.

The Keeley Neutrino Envelope Filter Auto-Wah Pedal is here. This funky, tripped-out circuit has been a decade in the making. Each opto-coupler is tuned to perfection and every Keeley Neutrino is like finding a magical vintage unit with that perfect tone, providing you all the classic, funk, auto-wah and Jerry-In-A-Box sound you've been looking for.

Keeley has used the classic opto-coupler design to add a rich and warm depth to the effect. The Envelope filter sound is an effect triggered by your pick attack or strength. The harder you pick, the harder it "wahs. Using the Neutrino you'll experience sounds that bubble up from a deep rounded warmth all the way to a shinning brilliance. Solo notes are individually expressive based on how hard you play. Create incredible vowel sounds a la "Let's get it on or chord-work "stabs straight from the disco dictionary.

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 as a way to make your wah sounds really mellow or really quaky. The Filter Selector lets you choose between three 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.

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.

      Comments about Keeley Neutrino Envelope Filter Auto Wah Pedal:

      Quality unit, excellent build quality, apparently useful in ways other than what I bought if for: a piezo enabled electric bass. I really wanted it to be better than the other auito-wah and envelope filters I was using, but alas, it was not, so it is now available for another buyer.

        Just as advertised! Very responsive. But Keeley can NOT call this a BOUTIQUE pedal when they use a 1970's feable cent clickity audible switch! Almost perfect!

          Comments about Keeley Neutrino Envelope Filter Auto Wah Pedal:

          Would love to give the Neutrino a positive review but it was defective out of box. The stomp box passes signal but the filter was not functioning correctly after trying every available setting and different guitars. Read elsewhere that these have an internal filter sensitivity pot that shouldn't be adjusted by the user. Took off the back plate and could see the pot but it looked to be undisturbed with the warning tape over the top of the pot undisturbed. At that point I gave up.

          Comments about Keeley Neutrino Envelope Filter Auto Wah Pedal:

          This pedal does what most want an envelope filter to do, plus more. I have used other envelope filters with my guitar for a funky or experimental sound such as the Bassballs, EHX Q Tron, etc. All of these pedals are pretty limited to the sounds that I was able to get out of my guitar. The Neutrino solved this for me. With many different settings to play around with, I was able to easily dial in tones that were immaculate. It literally sounded as if I were replicating my favorite funk groups with this thing! My favorite feature is the ability to switch the the "wah" sound to a reverse "wah". Trust me... this thing rules, although it is pricey, it was worth it for me.
