USB-C We were slow to move to USB-C, because the initial generation of jacks were not robust. Its a huge change and much more than just simple hardware swap. Moving to USB-C on Artifakt quite a bit of effort. The work around is not bad at all. We ship a USB-A to USB-C inside each new pedal. If someone needs one, we will send it. I am not saying this is a nothing sandwich, but we are trying to make it easy.
Bluetooth How many all-metal housed pedals have Bluetooth. Zero! This is a case of where it seems like "how hard is it to add Bluetooth???" It's very hard. The pedals that have it must expose an antenna somewhere (the H9 hides it on the display screen). If it were easy, Artifakt would have it. Believe me! Note that we have more wireless experience than almost any other pedal company (10,000 wireless Hot Hands sold.)
C4 v2 In discussion obviously but not being actively worked on.
