Hi @Nosupervision,
From memory you’ll need to download three things:
1. the V2 firmware for the G3n
2. the editor software
3. the zoom effect blocks.
once you have them, make sure your unit has the v2 firmware.
Then open the software editor on a windows PC. What it does is allow you to create a customised version of V2 firmware in which you can delete unwanted effects and add other ones (including bass ones) .
Once you are happy with your custom list of fx you save it as a new file and then use the firmware update process to load it onto your machine as a custom version of the firmware.
This is what I did, happy to give you more detail if you want but please proceed with caution and of course if you’re not comfortable with doing this probably leave it to someone familiar with computers! I am not a computer genius by any stretch but it worked for me… but of course I can offer you no guarantees, just sharing my experience
