I have tried a cyber twin at a music store about a year ago to try out a guitar, so I really don't have intimate knowledge of what it can do. I would try the bass down almost off, the mids around noon and the treble about 8-fullblast. The only factor would be how the tone stack interacts together (or if it even does) to get the sound like a vintage twin. I would try those settings as a starting off point tho...Good luck!
