I totally agree that auto volume needs to be brought back. I don't see why Line 6 didn't put it in right off the bat. I've thought about getting my m5 repaired just to get auto volume.
I see a trend here... auto volume needs a return(with picking dynamics) and some new verbs ( ethereal stuff, mods and what not)
Id love to have a reverb with chorus in the trails but it would be awesome if you could pick your mod. i.e. tremolo or vibrato in just the trails would be so killer.
