I thought you might like to see this board I put together recently. Four sounds from one guitar. Using the Sub Pro two separate groups of strings are isolated from the is acoustic guitar and channeled to two separate guitar pedal signal chains. This augments the acoustic guitar pickup that is also feeding a fork in this signal chain that provides an infinite sustain using Gamechanger Audio's Plus Pedal. Don't worry if that melts your brain. Take a look at the video and hopefully it will be a lot
