Electro-Harmonix Andy Summers Walking on the Moon Flanger Review
Our Verdict and Review Summary
This is a vintage-style flanger with a very watery, chorus-like sound. You can also get some shine out of it which pairs really well with a reverb trail if you add it with an amp or different pedal. Fans of the Police will find some added value here.

After I tested this pedal some of my buddies told me to compare it to the old Electro-Harmonix Mistress flanger. Since I don't have that pedal in my collection, I just checked out some videos and it seems like the Walking on the Moon is sort of a mod of that pedal.
There's also a newer version of the Electric Mistress, which I haven't tried. That said, I'm getting the impression that the Walking on the Moon is sort of building on the tone and style of those older EHX flanger pedals.
They all sound great over a clean tone.
It's definitely not a modern type of modulation. For example, compare it to something like the PRS Wind Through the Trees flanger.
That pedal is in a different world entirely.
But the WOTM is designed for a different style, and it handles very well in that context.
Details in the paragraphs ahead. Enjoy.

Tone and Sound
I started by taking some time just to play this pedal in its out-of-the-box form. In most cases I don't like high-rate modulation, and that was true here as well. Unless you're after more of a detune sound, I'd say keep settings tame, because that's where this flanger really excels.
Note: In-house audio demo coming soon.
It's one of the most chorus-sounding flangers I've heard, perhaps even enough to be considered a chorus/flanger combo.
And that's pretty common for these earlier modulation sounds.
It's definitely a '70s guitar tone.

It's quite vintage with some beautiful analog tones, but can also layer a clean signal for just about any style.
Style and the Filter Matrix
And while it's not particularly style-flexible, you can pretty much use any kind of modulation in any context.
This is helped by the Filter Matrix switch, which lets you disengage the movement of the flanger, producing a fixed filter effect. It's kind of like having a chorus/flanger without the waveform movement, which is great for layering over a plain clean signal.
This type of modulation can be helpful in any situation.
But if you're talking about the WOTM's "wheelhouse," it's definitely more comfortable as a vintage-style effect.

The Filter Matrix lets you turn off the waveform movement, which gives you a fixed filter effect.
Controls and Flexibility
The Range control functions kind of like a depth knob on a chorus pedal. On the WOTM flanger, it controls how wide the sweeps get on the lower frequencies. There's a lot of flexibility here, especially if you want to tinker with some detune sounds.
Color is a broad intensity control, while Rate takes on the expected roll of sweep speed.

The Filter Matrix is the main attraction, but there's enough control here to give you some room to work.
I've already covered the Filter Matrix, which is a unique feature that I'd love to see in more modulation pedals.
My main complaint with the control scheme is the lack of a wet/dry mix.
The Color control sort of takes on this role, but a dedicated wet/dry mix is something I always look for, especially in a modulation pedal.

A variation on the theme of the Electric Mistress with some new tweaks.
Dry/Wet Outputs
Electro-Harmonix splits the dry and wet signal with two different outputs, though is only implemented if both are connected, allowing you to only use one if you prefer.
Price and Value
The asking price for the Walking on the Moon flanger is fantastic. In a world where we see a ton of pedals for $300 and up, you can grab the WOTM for $130 and call it good.
Keep in mind, pricing is always subject to change, which is why I put up the live price guide earlier.
Make sure to check that and do some other comparisons.
But I have no issue whatsoever with the price. It's a great value.
Wrap Up and Questions
Electro-Harmonix has struck a good balance of price and quality, giving you analog tone, and even some extended controls.
Here's a quick review of the "ideal buyer" considerations:
- Vintage tone lean
- Filter Matrix switch
- Chorus-esque
These are the highlights that I think you'd be paying for, so give them some thought before pulling the trigger, and always think about your own situation. Not every good pedal is automatically good for every guitar player, so you have to bring your unique needs/wants into the equation.
