New Here! also "That Acoustic Sound"

[looder]

Hey guys, I'm really new to Mixing/Recording and since it's summer time now, I'm going to have lots of time to spend on it, as i'm eager to learn hehe
My music style is the Dream Theater / Opeth / Porcupine Tree kind of music,
Progressive and stuff.

So first of all i'm happy to writer and would love to get among the forum

To my question, I'm reading here a lot and you usually I found the answer for all of my "how to get this sound" questions but just couldn't find the answer.
I'm looking to get the Acoustic sound like in the very beginning of Wither by Dream Theater.

Thanks in advanced, And I'm very glad to write here!
