I just rediscovered this pedal while I was looking for alternatives to the EHX Attack Decay (which is cool but janky in typical EHX fashion), that aren't 7 million dollars for no reason. (Boss Slow Gear has entered the chat.)
The Layers pedal looks really interesting, and the price isn't nuts, but it doesn't do the simple thing I initially hoped it would do: apply Attack and Decay to the actual notes you're playing, a la EHX Attack Decay. As far as I can tell, these controls are only used to shape "layers" after the fact. Bummer, as a slightly more compact Attack Delay with added freeze and layering features (and if I understand correctly, reverb and delay of some kind as well?) would have been awesome. Definitely a fair trade vs. the onboard fuzz on the Attack Decay.
Ah well...
