Hi Guys
Regarding the preamp and new tube "sag": My first impression is that there is a marginal grid-stop value that needs to be made higher. new tubes have a bit more gain, noise, and brightness than ones that are broken-in. That gain difference might be exposing the marginal grid-stop.
You might be able to set up SUS-2 to do this but it would take some tweaking and it might have to be wrapped around two stages, for example the input cascade.
Regarding your effects unit: Spectral compression has been around for a long time. The simplest way is to split the forward path into separate frequency ranges, then give each its own side-chain for control.
have fun
