I had a quick look at the Maven Peel site. They have an interesting take on their Tweed Deluxe by using EL84's - easy to overlook power tube choice.
"Vintage tube amps typically produce about 20% sag, while more modern transistor amps produce about 2% sag. Modern attempts to produce sag, such as adding solid state or tube rectifiers, yield sag rates of approximately 5% and 15%, respectively."
I wasn't aware that adding a tube rectifier was a modern attempt to produce sag. They certainly have some unusual ideas.
