I got a DSP Error on my KPA about 2 or 3 weeks ago and sent it back to Thomann (Kemper Support said the DSP was faulty). They received the KPA june the 11th. I asked Thomann when they think they'll send me my fixed KPA but no answer.
If it happened to you, how much time it took to have your KPA back to you ? I have a gig june the 30th so I would like to know if I can expect have it before this date.
