In April 2005 Vettaville.nl posted a video with a Whammy like effect using the tone selector switch on the Variax. The demo was performed by Ron Huisen; Product Specialist for Line 6.
There have been several requests to explain how to do this. Here are the patches (tones) for Variax Workbench that you should place in order and upload to your Variax accordingly. Then you're ready to do the trick.
Go to Vettaville.nl to see the video and download the tones.
