Got a few Marshall Cabinets, decided to try out the matching 'A' box, for the ORI50H. I like it so far. Looking forward to seeing how it holds up in the real world. Regarding the building materials and speakers. MDF, yes. The G12E-60 speakers in the ORI412A look reminiscent of the 1990's Marshall "Gold Back Series" Celestions in my JCM410B. It looks like it was put together well. The tolex feels very soft and I wouldn't have expectation's of it looking good for long, being moved around, without a cover. I like the 800 era style single speaker jack. This cabinet does have the feet which have receptacles for Marshall casters. In the initial move from truck to house, indication is yes, get some casters. Skid trays are absent from the roof of the cabinet. It's 30 pounds lighter than my old 1970's Big M 4x12 cabinet. With judicious used of dollys and moving blankets I was able to get the ORI412A into the house. I made a sample video of me noodling a bit on the low five watt setting. With this cab, it's a loud five watts. I may be able to revert from the 50 watt setting, to the 10 watt setting, for shows. Looking forward to cranking this bastard. To sum up my first impression- Sounds like a Marshall to me.
