I'm possibly a little weird.
My Preset 000 is an acoustic patch that features a Left/Right channel seperation, as all my guitars have a Piezo pickup retrofitted.
The left input channel has no blocks in it and can be bypassed with a Volume block; the right input channel has the Piezo signal split into an enhancer block and two parallel PEQs. It also merges both magnetic and piezo channel at the end of the grid, followed by a volume block that is permanently mapped to an expression pedal so that I can always control output volume.
I have this as preset 000 because this is my "base template" for making other presets. Even if I don't use the piezo in a patch, I usually keep the piezo row alive, just so I can enable it with just the hit of a button in case I need it later.
