I built a Tweed Deluxe clone, which I still have about 17 years ago, so I say this being extremely familiar with the amp... My one wish would be a ceramic Jensen speaker model like a C12N, as that's the Neil Young speaker.
There's a weird phenomenon that happens with a Tweed Deluxe. Many people say it's the "interactive tone controls", but it's actually an effect of the cathode bypass cap on V1 not being big enough to filter down to DC. What happens if, you plug into the bright channel, keep the volume all the way down, the turn up the volume on the normal channel and you hear this bassy muffled sound. What is happening is.... The cathode of the bright channel and normal channel share the same cathode resistor and cap. The cathode of V1B,, in this case, is driving V1A with a 25uf cap to ground or a low pass filter creating this muffled sound. On a Plexi or Bassman, the same setup is seen, but the cap is 250uf or 330uf, so it filters everything out. The point is .. This characteristic is modelled well... And you can use this as a primitive bass boost control.
