The software is free ... you just can't use the HD with your model! Go to LineSix.com and you'll find it there. You DO need a USB interface or a POD XT to activate it though .... there are SO many tweakable parameters. You gotta try it. At worst, the $99 for the USB interface will be all you need to spend if you can't borrow and XT.
Everyone, and everything I listen to is my teacher. Every instrument, every voice, every sound in nature ... they are all my private tutor ... 24/7 for free.
