$145 shipped conus for sale is an absolute mint Robotalk 2 twin envelope filter. great pedal, two adjustable filters, lots of control, high quality build like all Xotic products. this unit was opened, used only for about 2 hours in home studio--you'll be buying a like-new unit in original box without a scratch. I'm only selling because I just bought a synth pedal that can also generate a env filter sounds. if you want to hear the great sound this thing generates, just check out Travis Carlton with the Larry Carlton trio on YouTube. . . seriously funky.
