I still cant get the hang of the AGS
Turning on the AGS instantly narrows the voicing of the TH, removing a lot of top end and a bit of deep bottom. It's still pretty flat all inbetween however, so that's why I think a lot of people might be turned off to it initially, at least if they are afraid of twisting knobs! Most pedal manufacturers that release something that has a narrow voicing like this typically make them with a heavily contoured EQ also. Think about the VT Bass, Sansamp, MXR M80 (with that color button engaged), etc, etc. all VERY scooped in the mids, highly accentuated hi-mid peak, and a tight bottom with a lot of low mids. The TH doesn't just do that automatically when you engage the AGS.
The complaint of those other pedals I mentioned is usually that they suck out the mids and you can't get them back. The complaint of the TH is that it is too mid-heavy. IME it's much easier to remove the mids to get that contoured tone from the TH than it is to put mids back into the tone of those other pedals. YMMV, but just try twisting the knobs and see what you get.
Some things to try:
1) With the AGS on, try leaving the mids flat, and just boost bass and treble to create a natural scoop.
2) Leave bass and treble flat, and scoop mids. Choose a Mid Freq setting around 1 to 3 o'clock and see what you get.
3) Then try combinations of the two above. Just play with it until you find something you like. Remember that using the settings on a gig is the best test. I've loved some of those pedals above at home, and then fought them on a gig. I've been less "Wow'ed" by the TH at home, and then found that it slams on the gig. My ears aren't the only ones who have noticed this. Engineers have generally been more receptive to the TH than any other preamp/DI I've ever used, and I'm not just talking about the run-of-the-mill bar gigs, but professional use cases.
