So this is kinda cool. Sold the Jube as I needed funds to feed other hobbies, and then purchased this. A Mint used 2010 1960A cab. As usual with the standard 1960s, I typically fabricate a new back panel out of Baltic Birch to improve the sound replacing the typically stock MDF back panel. I really liked the way this cab sounded at the store, hence buying it, but then today out of curiosity I decided to investigate. As you can see by removing the jack plate one can plainly see that it came from Marshall stock with a Birch ply back panel! Bing! Weird, I had bought earlier a 1960 'Vintage' cab earlier from GC (had it shipped from another store) that sounded horrible and stunk from cigs really bad. It had particle board back panel. I returned it immediately. One would think the 'Vintage' cabs would have been made to vintage spec hence the all Baltic Birch construction like from back in the 1970s..but nope. I now think Marshall does production runs with whatever materials are available. MK2 Steve if you are out there reading this you've been vindicated! lol You were totally right man.
