Hi guys
I recently purcahsed a BOSS me 25 with the usb connection and was wondering wether or not i could use this with eather amplitube 3 or guitar rig 4. Not sure which one to get and hopefully save a bit of money to just buy the software.

All so any recommendations as to which one to get.

That depends on whether the me 25 allows audio streaming through the USB or just midi commands. So read the manual.

Between Amplitube and Guitar Rig I would download buy Guitar Rig.
Dear God, do you actually answer prayers?

Yes, but only in a way indistinguishable from random luck or the result of your own efforts.
