True Envelope Filters

I don't really understand the build-up to the question. I'd call the Mu-Tron III, the Mu-Tron III+ (which everyone here hates passionately), the Electro-Harmonix Q-Tron, Q-Tron+, maybe the Bassballs, and so on envelope filters.

Or, EHX (Electro-Harmonix' abbreviation) makes a rack-mounted envelope filter that is beau coups expensive, and rarer than a Bass Micro Synthesizer, Stereo Polychorus AND a green Sovtek Big Muff in the same store. That's all I know about it.
 
My understanding is that it is appropriate to call an effect an envelope filter as long as it uses an envelope follower to determine the volume level of a signal, which triggers a filter sweep. This is as opposed to manually sweeping the filter (as in a wah pedal), or using an LFO to sweep the filter, which is usually called an auto-wah. In that case, all of the pedals mentioned above qualify.

That's exactly what Higgie was talking about, unclejam.

Envelope filters include the qtron, mutron, maxon af-9, auto wahs include the boss aw-2 and some others...? lol

That's what I was getting at. Envelope filters are controlled by the volume of the signal, therefore, the harder you dig in, the more prominent the effect.

Another example of an auto-wah would be the MXR Bass Auto Q in it's "shimmer" mode. You set the rate, and the pedal automatically wahs back and forth. Like any modulation pedal, only with a wah sound.

unclejam, I'm a he by the way...lol.
