I'm taking a little time out from my session to destroy my system performance by launching the browser

. If I wait any longer, I'll forget some key points of what I have learned so far tonight about TH1.
I did find the manual, which installed as part of the demo installer, and it is extremely well written and absolutely essential -- I doubt anyone could learn how to use this plug-in without it, as there is too much locational context and mouse sensitivity on single vs. multi-clicks for blind experimentation to be likely to be very elucidating.
Please disregard my comment about selecting the 70's setup to get a dry sound for neutral evaluation of the core amp modeling engine. The performance of this plug-in is not very good on my box; nor does its entire GUI show up or allow me to resize or move it. So now that I've read the manual, I understand the top panel better, and realise I was on some random factory preset, one of whose eight button-shortcut variabts happened to be dry and was labeled "70's". Each preset has different variants (or none at all) and different labels for them.
My hopes were dashed though after exploring all of the available effects, as someone had written (elsewhere) that it had a Talk Wah effect, which of course I was hoping would be more flexible than the one in Guitar Rig 3 (currently the most advanced Talk Box emulator available as a software plug-in). This turned out not to be the case; though it does have four Wah-wah variants, one of which is a simple Mu-Tron type.
At any rate, I am impressed now by the interface and its flexible routing. It just takes some time to learn the unique paradigm, but it becomes intuitive quickly and results in less clutter, more focus, and a clearer overview at appropriate levels of workflow, than any other current guitar effects suite IMHO.
There are eight amp models available, with obfuscated names but pretty obvious in each case. There are a couple dozen or so mic models to choose from, but I haven't gone through them thoroughly yet to identify them all (some are very obvious). I think the ribbon mic they advertise in their marketing hype is probably an AEA model.
I haven't done any sound evaluation tonight; I'm just trying to learn the interface visually. I think due to how much time it takes to set up a good preset, I'll probably just run through some of their factory preset examples first, and then do some of my own to match settings that I had already come up with on AmpliTube 2, for direct comparison. My main task tonight was to learn how to work the plug-in GUI so that I know how to create setups, and it's actually way easier than the other guitar effects suites as no workflow, order, or hierarchy of editing is imposed.
At each point in the signal flow, you simply right-click to bring up all available choices. ou don't have to enter a specific module to have access to effects vs. amps vs. mics, for instance. I think this is a refreshing approach, as someone who wrote MCAD software for many years and heard customers complain about the need for after-the-fact ability to edit a top-down model from the bottom-up, or even from the middle. That is, support for arbitrary editing.
