One thing that would really come in handy for me and I suspect others: I usually have my main guitar and a backup for shows.
To keep them always connected I use a switcher and If I need to grab the backup guitar I just change the active input on the switcher.
I use a dry-wet configuration on my main preset and If I connect Main Guitar to Input 1, backup guitar to Input 2 and choose, on Input Block, “Input 1/2”, each guitar just goes into the panned channel on the grid. And I understand this as this is considered “Stereo Input”.
What I would like is that make it configurable - something like “Input 1/2 (Mono)” or “Input 2 = Input 1”, so I have both guitars connected, use the same preset and avoid an additional guitar switcher.
My workaround (to avoid the switcher) was to duplicate the presets and choose Input 2 on the copy. If I need to grab the backup, I change the preset but it would be nice if I just can use the same preset.
