Last last year I bought a B-Stock Analog Four Mk2 and has an issue with LEDs flashing randomly. Took weeks back and forth with Sweetwater to confirm (it would happen sporadically) and weeks to get a response from Elektron. I diagnosed the issue a week after I got it, and since it was B-Stock and they had none left, repair was my only option. I sent it in almost 3 weeks ago and was told to expect another 3 weeks for repairs.
I’ve been dealing with this issue since December 17th, and I’m not terribly happy about how Sweetwater or Elektron have handled it.
