If they release a rack version Ill be well pi#?ed off I only just brought my kemper before Xmas asked in all the shops that were selling them about a rack version they said no its not coming yet. all the features on the KPA at the moment don't work eg performance mode and undo and also there is no foot pedal available yet. They should sort this out first. I think it's rack ears for the kemper or the amp for the hole in the back
Even if a rack version is announced, I would'nt think it would be ready for market until summer. (IMHO) I cant imagine them fitting all these knobs into a 2U interface. I like the way it is now.
If it is a rack version, I would hope that a controller of some sorts is coming with it.
