Some things I picked up while doing the acoustic arrangement:
- One way to accommodate two acoustics is to have both play open chords, using capos. Here, I recorded one acoustic with the 'D G A Em' chord shapes, and the other with the 'C F G Am' chord shapes.
- Vary the volume of your acoustic to give the song more feeling. Or just worship along, it'll come naturally. :)
- Use a compressor with acoustic - helps to prevent clipping.
