It's not available from Line6.  And they never have offered it before.  This is assuming you haven't downloaded the models pdf which offers some of the information you're looking for but not nearly as in depth as you want. Look in the manualsdownload area if you don't have this pdf.

With my limited knowledge of tube amps, I think that information is about the tone stack of each amp. Since almost if not all tube amps tone stacks are Passive and not active, you really should be looking for information about the tonestacks of these amps. With a passive changing any tone controll doesn't only effect that tone control, but it effects other frequencies...Anyway I found this tonestack calcutor progarm. http://www.duncanamps.com/tsc/index.html

It worked on my windows XP, and it's very interesting when you run and start simulating what happen to the EQ cruve as you move the bass or treble etc. It has simulations for Marshall, Vox and Fender, but I found it very helpful in sheding some light..It took a second to download and another 2 seconds to install and run, very nice little tool...
