Based on your reply, I am planning to purchase SKB 1SKB-19-P12 case, are you certain Qu-16 will fit in this case?
I have an older version of this case- SKB 1SKB-19-P12 and its where my QU16 now lives. But since the QU has that unusual design, it is a bit too tall for the case. I had to pad mine and it now works quite well. However, if I were buying a new case I’d probably find one that fits the mixer without any customizing.
