This is the more extreme version of the Pale Green comp. It's got a Decay control, so you can tame it to a regular amount of squish with that, or alternately you can dial in faux-feedback and 'breathing' type tones at higher settings. Handy for slide, tapping stuff etc where you really need every little note to come forth.
