The looper function of the Kemper is very good !
Being able to toggle PRE or POST is drfinitivrlly an usefull improvement.
For Me, the better choice is to use the (down) \/ button on the remote to toggle PRE/POST while in the Looper mode.
In Looper mode this button is not used anaway, and it can be an improvement as I (and other people) offen change the Looper PRE/POST settings.
