Just adding some ideas to the list here, humble requests if you will.
Marshall Mode 4 head and cab
More bass amps and cabs and pedals,
More eq options
A block memory of some sort, so when i use that same block somewhere else it keeps the same settings without needing to copy paste a million times.
I feel like the seek wah doesn't really work that well, zoom did a really good version of it in their gear, maybe fix that please?
Model some reverbs please, there are alot of great reverbs out there. Or make more reverbs with fewer adjustments.
A helix expansion bay for more effects loops, I'm using all of mine (for bass pedals) but i could use a few more. I would be willing to buy an external piece of line6 gear (I'll spend more money for this). Maybe something that could connect through usb? Or the variax port, or something.
