there are no such thing as jtv tones... the guitar models will work in the jtv's and the older variaxes...

the difference however is the JTV renders the models at a higher resolution...

so a little better quality there.. plus the jtv components such as the bridge and pickups have been upgraded to work a little better as well.

there are some obvious exceptions...

such as you can't use an alt tuned 12 string model on the older variaxes (the 12 string is already technically alt tuned)

the group you posted this to "Variax Guitars" is a user group... (as in not a support group)

and as such line6 wouldn't read/answer and you cannot mark this is a question to get their attention...

just in case you were wondering why the answers came a little slow....
