Here’s a recording I did with the Neo Ventilator into Garageband, with just a touch of eq added.

I recorded the two channels coming out of the Neo Vent into a stereo track, although I may be a better approach to take two mono channels, so the width can be varied easier for a stronger effect.  Not quite happy yet with the slow and fast speeds of the rotors nor the rampup time, I’ll have to experiment with that some more.

Jim Alfredson has done a great review of the Neo Vent, and seems to be able to record a more pronounced effect from the pedal, I’ll have to try and figure out what he’s doing different.
