I found this page: https://guitarpatches.com/patches.php?mode=show&unit=G1&ID=5702 It may help to get you started, but I am also looking for a better patch to make the guitar sound like a bass, or use a bass with this pedalboard.
Im able to import some of the effects in a B14x to my G14x by changing the extension from .zb1x to .zg1x but most of the effects are only available on b1... I wish we could sawp the software for it appears to be the same hardware - but hey it would be bad for Zoom business...
