I have just purchased one of the hard to find left handed Variax 500s. I would love to have a newer model but they just won't build one. I have a POD HD 500X and XTLive. The guitar came with the Workbench interface. I want to restore it to factory settings then build my own guitars and patches for the POD. Can I use my POD HD as an interface for Workbench ? I guess I need to get a manual for the Variax if one is available online. I'm excited to see what it's capable of. Any suggestions welcome.
