Indeed analog series of mignature EHX ... it matches the Doctor Q.
The settings are the same, a knob that sets the position of the Wha and a selector to "boost" the bass.
Alim in standard Boss type 9V.
CAN NOT BE LESS

UTILIZATION

It was a sound, ONE ...
We choose the position of the end, I left the selection board to boost the bass on all the time ...
S'aurait been a little more complete ...

SOUND QUALITY

I bought this for use on a few tracks. it's pretty much what I expected from an Envelope Filter.
I find the sound really nice rhythm on clean (and not just for the funk!) Ca clean spice up a bland (but I is not clean my fade ...)
In distortion, it's really cool, I bought it for that, have a different sound on a lead or a soli ... is successful, I do not ask him any more ...

Very nice effect on BM

OVERALL OPINION

I just receive it.
No special really unpleasant for me.
This is an effect that has personality (maybe not as much as the original but I can not speak, I have not tried)
I tried this because I needed an Envelope Filter EHX and I like in general, I had not tried or compared to potential competitors.

The price is really attractive (to a factor of purchase), as in the whole series Nano brand.
