At first Congrats for your new CAPS release!

I have a couple of questions for you, namely:

Could you please elaborate a little more on the new amp model? i.e:

Is it based on real measured data as opposed to spice simulations?

If it's based on a spice simulation did you implement a simple valve
stage or a complete preamp made of multiple stages?
The power amp section (valves & OT) doesn't seem to be there anyway
AFAIK, but maybe you implemented it with a  transfer function of your
real Fender amp that does from the input jack to the OT/speaker?

I am browsing the source code right now and can't easily figure out
which 12ax7 model you're finally happy with... there are multiple ones
in TwelveAX7.h

I am asking this as I'd like to experiment with it a little. I still
think there are issues that prevent obtaining more "M*rshally sounds"
or high gain sounds in general.

Thanks in advance.
