The last walkabout was made in May 2017. Here is my 01-11-16 that just came back from Mesa a few days ago. I bought this one in 2016 and never used it...I had 4 of them. Last month I went to use it and there was no sound? I sent her back to mesa under warranty and they found a bad chassis fuse and a bad tube. Mesa put a new fuse and 2 new tubes in her and she is good to go. My cost for the warranty was $60 to ship to them plus $36 for 2 new tubes...tubes are not covered under warranty, not bad at all!! I will PM a photo of my Mesa receipt to the buyer. I have not opened the box...you will get her as if shipped from Mesa to you! No scratches or wear, as new as you will find without buying new.Price is firm plus actual shipping.PM me for shipping.
