Just to clarify:
I agree that the implementation of the AGS footswitch on the TH pedal is not ideal...and that Aguilar could have made it more useful.
I just don't agree with posts which present this great-sounding preamp as (almost) unuseable because of this "imperfection"...
It's quite easy. If you're sensible and intelligent, you gather information before you make a purchase like this. In that context, you will pick up how the AGS works and make a decision of whether you can make that work in your scenario or not.
If you regard it as a single channel preamp, it is a great pedal. Robust, good EQ, nice baked in sound, good DI, great drive sound.
But when you're like me, you look at the pedal and proclaim "Yes! They have solved a problem of mine! Running the Tone Hammer head, I would have liked a foot switch that lets me add some drive, because while I really like the drive sound from the amp, I don't want it on all the time - and I hate to twiddle amp knobs mid set, messing up the levels.".
I looked at it, saw the second foot switch, and just assumed things.
Furthermore, I do have the required amount of arrogance to then proclaim that my interpretation of how this thing should be is the right one, and the way the Aguilar engineers envisioned it is wrong.
You can't really use my line of argument without obscene amounts of arrogance.
