How do i become an active user?

Do i need more posts?

Also i just bought an ibanez guitar used from guitar center 2 of the strings are lower than the rest and i cant tune it properly im going to return it for a refund.

is that a wise choice?

I'm about to buy a new Ibanez from amazon and I'm wondering can i use some sort of plugin with a Digital Audio workstation to just plug my guitar straight into the computer and not have an amp but still have effects?

or do i need something like the pandora 3xd (i think its called).

Thank you for your help.
