I tried the freeby version of Tonex. Of the 20 amps, only found 1 amp I think I'd use, then dialled in a better equivalent on my Kemper in about 1 minute.
QC was hailed as a game changer, look what happened there.
Tonex is the new "game changer". It beats pedals like the iridium I would think, but it's limitations mean it's nowhere near a game changer for pro use imo.
6 months time a new "game changer" will be out
Kemper will keep doing it's thing.
