Very cool pedal from EQD that is now out of production. It’s a harmonic tremolo but with its own thing: an phasey LFO that can be attack-sensitive, as can the amplitude effect. You can get trippy ramping effects where the tremolo speed will automatically fluctuate based on your attack.

Purple sparkle enclosure, a beaut. Comes with original box and Velcro on the back of the pedal.

From Earthquaker:

The tremolo can be subtle and shimmery or full-on throbbing depending on where the depth control is set. With the depth set to zero, the Night Wire will act like a fixed filter, phase shifter or envelope-controlled filter depending on which mode the filter frequency is in. It also features a cut/boost volume control to get your levels just right.
