I was trying to read the specs. I think it says, "Cornford MK50HII Clone" on there somewhere.....
If it is "what it is" though, they should just come clean with the specs/marketing on the amp and not cover it up. If Cornford closed the doors and Paul/Martin licensed the circuit, they would be miles ahead of the game in bringing the amp public. All one has to do is Google "Cornford Jet City" and this link comes up first. They could just sign up and respond.
Some slippery slopes going on behind closed doors. People think we don't know.
