This is my first marshall amp and i happily bought it. Looks really cool with the partly gold colour. Every single knob does its job. There is nothing wrong with the amp by the means of electronic or mechanic. Panel on its back feels thin. Well, not like it is going to break with a slight touch. But...
When i first plugged my tele into the amp immediately heard the hissing in the background. Even on lower volumes there is this hiss and i dont even need to mention how does that hiss sound on higher volumes. If you are obsessive or audiophiliac, you are definitely going to feel uncomfortable. With a headset, hissing sound gets more tolerable. Tried with different guitars and sockets, nothing changed. Need to add, while playing focused of course, guitar sound dominates hissing.
Beside everything, cleans are great, gains, od's are great. 4 channels to use and save your own manual settings. Physically larger than i expected.
Final thoughts, no one can deny, amp sounds good. More than enough for couch play. Looks good. But that little hissing sound might be a deal breaker for you. Personally i dont mind but its a subjective matter.
