Glad you like it Marze hope it helped. Here's another great technique. After recording your acoustic, double it. Then if you have another acoustic guitar put thinner strings on the E A D G strings tune just these 4 strings up an octave higher. It's great like a cleaner 12 string sound when mixed. This video will explain it a little more. https://youtu.be/pRKDOiUMbAQ Start watching at about 6 mins in
Nashville tuning. I didn't watch the video, but the usual method is to play the part on the normal strung guitar and the Nashville strung guitar and pan the two tracks hard left and right to give the feeling of a stereo 12 string.
