I don't really care about a looper but want a pedal that is laid out like the Kemper itself. I am not a fan of the FCB1010 and would pay good money for a well-built foot controller that connects with one cable. Some of the other pedals would be fine if they connected with one cable but I'm not paying a grand for a controller that needs 3 cables. I don't want to control anything else but the Kemper. They started talking about designs for a foot controller a couple of years back. I don't care which one they go with, just pick one and release it. I can plug in expression pedals if I need them so don't care if they are included or not. Also I'd prefer a footswitch that doesn't require me to wear cowboy boots or any other pointed boots for that matter. Put an extra half an inch or so between those buttons although that isn't that big of a priority.
I'll probably pay whatever they ask. Hopefully $500-600 if it has 2-3 rows of 5 buttons. Maybe up to $800 if it has a couple of expression pedals. Lower is better but quality components are worth a extra money. I spent a chunk on the Kemper vs paying much less for a Line 6 or similar amp modeler. I'm not going to skimp on a good pedal board.
