I had one years ago. One of the original blue speaker versions. Wrapped it in plastic and left it in the shed before going to University for 4 years. Never took much notice in the years that passed until a friend of mine wanted to try one.
Went to my parents to dig it out for him only to find it missing! Come to think about it, the shed it stood in was also missing !!! Apparently my parents had no need for the shed and believing that the AC30 was past its best (it did look a little 'road worn' to say the least), condemned it to the tip along with the shed...!!!
