I'd say I'm offering my 2 cents, but since I'm English, I'll only offer a penny for my thoughts:
Loads of people, myself included, have been asking for a Kemper profile player for years, but it took the ToneX pedal to be released for it to actually happen.
The existence of the ToneX pedal may have had literally nothing to do with Kemper bringing this out, but it does offer a significantly cheaper way for most people (who will never profile an amp) to sample what Kemper has to offer.
Liquid profiling definitely piqued my curiosity, and this product, at pretty much half the cost of a Kemper stage, gives me the opportunity to try out the Kemper ecosystem at a significantly lower cost, so I am going to give it a go.
I'm sure I'm not alone in this.
