Critic Reviews

Electro-harmonix Stereo Electric Mistress Review

guitarmasterclass.net

The Electro-Harmonix Stereo Electric Mistress offers a decent digital flanger/chorus experience at an affordable price, but don't expect it to replicate the lush analog tones of its namesake. While it outshines similar digital units in warmth, its stereo flanger and chorus effects sometimes clash in frequency, and the filter matrix feature is underwhelming. Build-wise, it's sturdy but lacks battery power, relying on a 9V adapter. Ideal for psychedelic rock, it struggles with distorted fusion sounds. Overall, it's a solid, if not spectacular, choice for those seeking compact modulation effects.

Electro-Harmonix Stereo Mistress & Holy Stain Review - Premier Guitar

premierguitar.com

The Electro-Harmonix Stereo Electric Mistress is a digital flanger and chorus pedal that delivers rich, organic tones reminiscent of classic artists like Andy Summers and David Gilmour. Its compact, robust design is a space-saver on your pedalboard, though it forgoes battery power for a DC adapter. The standout feature is its LED, which pulsates with the modulation rate, making adjustments easy on dark stages. While the lack of an expression pedal option is a minor drawback, the SEM shines with its lush stereo outputs that create expansive, 3D soundscapes. Overall, it's a fantastic update to a classic, offering plenty of tonal versatility at a reasonable price point.

Great flanger

Great flanger, no noise, no other problems the vintage mistress’ had. The chorus is lush and great to mix in with the flange. Stereo is cool, when you run it through two amp, makes a big and wide guitar sound. Love it!

moogbadger

Cool!

A very wide, warm and rich flange/chorus sound which can do anything from Robert Smith to the Smiths to Siouxsie to...

It can go really fast and warbly, or it can be subtle and shimmery. Below a certain 'rate', you can manipulate its comb filter for manual jet flanging, old-school goth style. Cool.

A word of warning though; this sounds very different to the deluxe Electric Mistress, which is a pure Flanger/matrix thing. A lot of people do prefer that one, and if you're after, say, the Gilmour sound circa 'Animals', that's the one to get, not this one. This is more of a dual-purpose chorus and flanger for all-round modulation duties. It's not the best chorus or flanger sound in isolation, but combined they're lovely.

cammojodragon

Some quality tones

There's a lot of interesting sounds to get out of the Electric Mistress, though the name may be somewhat misleading; the addition of a chorus pedal sets it apart from the vintage tone everyone seeks, and lacks the detailed controllability of other models. While it's simple design makes it easier to get a great tone out of, this isn't a pedal designed to do subtle; think Andy Summers/Police style tones.

Great for adding some extra flair to a rhythm section, but those looking for Gilmour-ish flanged lead tones would do better to turn to Mooer's ElecLady

jimmarchi1

my friend bought one of these back when it came out, I was really underwhelmed.... Mike Matthews rarely releases an effect that's not mind-blowing (even the ones that aren't useful are usually cool), but this was just a boring effect

bruce_kirby

Two for one

Why get a chorus and a flanger when you can both in the Electro-Harmonix Stereo Electric Mistress? You can mix the tow effects to get a unique tone and the LFO feature gets you a cleaner tone.

divuar_lacroix

Simple yet Powerful

This baby is the first pedal I own from EHX. A cool mix of Chorus and Flanger with only three knobs. Still, the controls are enough, plus there is an awesome matrix mode to create even more weird sounds. Must say it is well-made, tight and has huge comfortable knobs. I like how it looks in the pedalboard: the LED has few different states so that it shows not only the maximum position of the envelope, but also the mid-state. Perfect, will go for more EHX for sure!

ben_thies

Mono Inputs = Not Usable in Stereo

Having mono inputs limits this pedal a lot. EHX is assuming that this pedal will be the first in my stereo chain. They do the same with all of their other pedals. This means, if you're a fan of EHX pedals, you can only use one of their stereo pedals in stereo. Other than that... this is a great sounding pedal.

oasisroses

free your inner gilmour...

I bought this as a flanger for one song my covers band play. i didn't care for it mainly but its earned a place on my board as a keeper. as a flanger its great and as a chorus/flanger thing its great. as a chorus its rubbish... got mine cheap at 55 quid including the wall wart. its not the best 55 quid ive ever spent...(ive been to Amsterdam, but that's another story) but its up there.

dorgsan

Digital flanger/chorus pedal

Good: + Two effects in one pedal + Stereo + Great High Pitch Expressiveness + Filter mode

Bad: - Digital - Buffered bypass - No a lot of low end

pax_downunder

Great

I love the swirling or pulsating sound this pedal gives. Can shimmer on slow rates or wobble on fast settings, then you can mix a Chorus to it.

jimmarchi1

suck

I do not like the new stereo electric mistress... I do not like the new clone theory... I do not like what EHX is doing to their classic modulation pedals AT ALL. I can't give this thing away. I've sued it as a chorus on occasion on keyboards.

moogbadger

Yeah...I think they should have called it something else. It's nothing like the vintage Electric Mistress that true Gilmour/Andy Summers fans want. I just think it's a nice chorusy flanging thing, but it bears little relation to what old-timers would call a Mistress.

jimmarchi1

traded it ina big lot of junk for some other junk I might actually use

You’re known to have a real penchant for effects pedals. Don’t you have an effects loop on your Hammond?

Yeah. Bill Beer put that in. I didn’t know there was an effects loop in it. I thought there was a “direct out,” and then I thought that there was a “line in” in case I wanted to run the keyboard that was sitting on top of the Hammond into the Leslie as well. After I had it for about 10 or 12 years, I did a session with The Cult. Someone said, “This Leslie sounds so clean, can you distort it?” And I said, "I don’t think so." And they looked at my Hammond and said, “Oh, you’ve got an effects loop. Let’s get a fuzz pedal!” I was like, “What?” And I was off to the races. I started out with a little Turbo Fuzz, that I also used on a song on the album All Shook Down by The Replacements. Over the years, I’ve tried other things as well. I have a couple of pedals by Line 6, and Ryan Adams, God bless him, gave me a couple of Electro-Harmonix pedals like the Memory Man and the Electric Mistress flange pedal. I also have a tremolo pedal and a turbo boost as well. These are all for the Hammond, and I also use the spring reverb that’s built into it as well. Ever since I got this organ back around 1977, I’ve used this reverb. It gentles it up. Nobody can do what [Band keyboardist] Garth Hudson does. However, there are settings on that Lowrey organ he plays where the attack is a little softer. And that changes the effect of how you play. So I find that using things like the Electro-Harmonix pedals allows me to soften the attack. It’s fun. I even have a Line 6 modulation pedal on the DX7 to give it a little bit of chorus. That makes it tolerable. I also sometimes run my Vox Continental through a Leslie simulator.
