Hi William, I got an answer from a friend of mine who moved similar equipment to Ecuador. He said: “No, it shouldn’t be a problem. I packed several studio components in their original boxes along with some packed in moving boxes without incident . As long as it is used and listed as such on the packing list, it will be fine. Their declaration needs to include information about their musical work/hobby. You are allowed to bring in equipment that relates to work and personal interests, as long there aren’t (new) multiples. That shouts “resale”.”
