I Can't hear the Guitar Amps in Logic

Hi:

I am hoping someone can help me. I have my guitar routed into Input 2 in Logic Pro X.

I loaded an amp from the Library of amps. For example, right now, I have loaded the Amazing Tweed .

The problem is, when I record or play the guitar, I cannot hear it going through the amp. In other words, I can't hear the processed sound. When I play back something I recorded, I hear the processed sound.

How do i hear the amp as I am recording? All I am hearing is a clean unprocessed sound when I play, which ***** because I'd like to hear the amp I'm using.

Thank-you
