[ReWind James]

Hey pitbull check this i finally have the pictures in High resolution i bought the japanese magazine and it's not a phaser because it's not written speed at the bottom of the knob but something longer !

even if it's not wired it's still there.

it seems that it's a noise gate.

this magazine has a ton of infos and good pictures.

It's a Noise Gate. The text says "THRESHOLD" under the knob.
