This is an ultra RARE Death by Audio Phosphene Scream with the original box! Here's the full spec from Death by Audio's website!
Reverb: Fully counter-clockwise, the reverb is blended out. While turning up the knob it ranges from realistic hails to full on infinity caves.
Feedback: Controls the number of repeats and intensity of the echo. Turn all the way up for almost endless repeats. Turn down for no echo at all.
D-Time: Changes the time in between the repeats of the echo. Turn all the way down for metallic filter sounds.
