I'm following this thread (non-owner. maybe later). I believe you should get usable tones right out the box. Why buy something on the hopes you "might" get usable tone later? I though Kemper was a "guaranteed" tone maker. I've never had so much optimism and pessimism over a product before. UHG!
You can (and should expect to) get solid sounds out of the box. It *is* a guaranteed tone maker.
Some people don't bond with a certain thing.....and tell everyone they hated it. The ones who like and promote it are generally fewer. We're too busy having fun.
