LFO-controlled Auto Wah

What I am looking for is an Auto Wah that uses an LFO to control the sweep. Like a treadle that rocks back and forth on it's own, sorta.

I know EHX built one into the Frequency Analyzer, but I don't want the rest of that pedal for the one effect.

Does such a thing exist? A search of the effects forum was inconclusive.

Wait, doesn't an autowah use an LFO, by definition?

If it didn't, it'd be an envelope filter. :eyebrow:

The two are often mixed up and/or grouped together. But in discussions around here, at least, auto-wah pedals are LFO-based, and envelope filters can sound similar, but are not LFO dependent - they respond to playing dynamics, instead.

Well, I don't know that Wikipedia can safely be considered an authority on the subject, but it says that an auto-wah is controlled by either an envelope filter or an LFO, with the envelope filter probably being the more common. The example it gives of an LFO-controlled is the Boss AW-2. Hope that helps...

Yeah, I saw that. Wikipedia broadens the concept of an auto-wah to include circuits which feature envelope followers and not LFOs. But at least around here, the trend is to treat LFO-based and envelope-based ones separately.

It's an issue of semantics, but at least when it comes to searching for info on TB, using simply "autowah" or "auto-wah" should be good enough to find info on just the LFO-based stuff.

The AW-2 does do this, but my experience was a huge drop in low end. The MXR Bass Auto Q is the best you can get for the money! Fantastic pedal that can be an envelope filter OR an auto-wah. I've bought and sold 2 of them in the past - I love the pedal, but just never can find a use for it so have had to sell it on both times.

Okay. That really clears things up. I've had it explained to me 4 different ways by GC employees, and people at my local music store didn't really use those types of effects much (and we don't have a big demand, what with the scene being bluegrass, folk music, reggae, blues, and indie kids), so it wasn't really clear to begin with.

I also need to remember the Search function is only as good as the words put into it...

The Electro Harmonix worm has what you describe. Can be found for about $100 US.
"Modulation madness! The Worm is an all-analog multi-effects processor featuring Phaser, Tremolo, Vibrato, and the never-before-heard Modulated Wah. At the heart of The Worm is a specially designed tone-bending engine which creates groundbreaking oscillatory effects."

I too have been interested in a modulated wah. As just above I mentioned the EHX Worm, which I have and like for it's versatility and price. I have been looking for possibly a little more control in the modulated wah area. There was a copilotfx gyroscope listed on the buy adds. I haven't been able to find out much about it, other than a modulated wah. I searched a bit more and found the subdecay prometheus. I'm curious to personal experiences with it. Please post if/when you do go with something. Thanks......Lapicide

So I searched and dig this up:

Any good advice for choose an LFO-controlled wah?

Actually I want to add a delay before the wah , to create something, well, "won't get fooled again"-ish feeling stuff.

Please, enlight me!
