Can you give a link to zip file? Didn't see any Variax DLs when I looked on website, all for other Line 6 stuff.
My tutor had a play with my Variax yesterday, he really likes it, but said strings need changing already! I changed my PRS's yesterday after a month as they were feeling rough. He said that even playing hour a night, I should change both guitars every 2-3 weeks!
He's just ordered his fifth Stratocaster, a John Mayer US signature before they disappear. Mayer's passed me by, but as my tutor has a fair share of Mayer tattoos as well!, maybe he's worth investigating?
