if you load the firmware to your device it will be factory reset. But you can also then reset your device at power on - and you have the factory set.
+1 pretty please, I can see the Factory ones available for the G1X but not for this incredible machine!!
like "shooking_sybase" said if you own a B1/B1Xfour you can get the factory patches by resetting take a backup if you have customized any patches before resetting. My advise take the backup in both ToneLib and zoom GuitarLab.
I am gradually putting pedal resource.under here https://github.com/shooking/ZoomPedalFun If u know of other useful sites please see them to me - either post here or raise an issue on the git. If I have the pedal then I will put the patches etc in the git. Got rhythm working on G5n - will test of g3n and GCE-3. The B1XFOUR series are different.
