Description
Experience the luxury of resonant flanging with the Electro-Harmonix Neo Mistress Flanger pedal. This device faithfully recreates the rich, harmonic sweep that has defined the classic Mistress, presenting the full spectrum of tonal density that flanging adds to your musical performance.
The Neo Mistress is not just a nod to the past; it takes flanging into the future with its manual filter matrix, a standout feature that allows you to freeze the filter sweep and command control over it. This gives you more room for creativity and personalization, resulting in truly unique soundscapes.

Perfect Flanger Pedal
I love this pedal. I like simple pedals so with just the two knobs it’s great for me. The Rate is pretty self explanatory and works perfectly. The tone of all the electro harmonix pedals are very pleasant to my ears. This one adds that super cool “spacey” sound as much or little as you like based on what settings you use. Also, seems very interactive to the way I am playing. Couldn’t recommend it more.

Didn't Do Everything I Wanted It To
I had this pedal for about a week before ultimately returning it. It was the first flanger pedal I had ever played. It sounded good! I like simple pedals, but this pedal had me wishing I had more control over other settings.
The other reason I returned it was because it made a terrible high pitch noise whenever it was off or on. I tried switching everything around, different cables, etc., etc., etc. Just didn't work properly for me, but that doesn't mean it will happen to you.

For his 2016 solo set at Third Man Records, Mascis used the EHX Neo Mistress. This was possibly done because NEO Mistress takes less space than his usual Electric Mistress.
