@la szum was on to something in the FW thread. The GOT presets were super cool (though that Synyster Gates IR was um; a little weird?). FX block libraries were seriously icing on a delicious cake. A TON of the other artist presets as well as the stock ones are good as well.
For me; the best way to approach ANY FAS device is spend a day or 2 going through the presets. Pay close attention to the presets AND FX that catch your ear. When that dust settles; blow the whole thing ALL TO HELL and create your own presets. Whether it's tweaking an existing preset to personal perfection OR starting 100% from scratch. So overwhelming if you are a fan of having options at your disposal. Even on your 3765th go round
I could make a personal case for myself of clearing all on device presets and just putting the few on there I use in whatever regular use case. Too much of a good thing for my temperament
Figure out the way you want to handle switching (and if you're like me; make the layout the "For dummies..." edition). Copy that layout globally if you have to. Panic buttons should not be necessary. Rinse repeat as needed.
