My main gigging amp is a 7400 dbs. I also have a 7200 as backup.
As lozz says - loads of welly and really great tone.
However, it’s very heavy and when I travel abroad for shows and gigs with provided cabs, I take my tc mini head. I can get close enough to my recorded sound to keep me happy, and Johnny punter doesn’t really notice 😉 plus it takes minimal space to carry 👍
My first choice is always going to be my Marshall, and I do use it wherever possible.
If I found another 7400 I would be all over it.
Imo very few amps come close tone wise to it.
