So i have a line 6 fbv shortboard like the one below:

And i do not know what the two buttons (function 1 and function 2) do so could someone tell me please? They are the ones left of the screen.

Thanks in advance.
You can asign a funtion to those buttons through your computer (if you don't know what to do with them). That pedalboard has a USB jack to connect it to the computer, so you can use the FBV software in order to do it.
