@laxu great write up, can't believe I missed it! I've been hoping for a decent (recent) write up of the A2S on this forum. Its flawed but fantastic!
I've come from a Strymon Iridium which I sold, I got a bit tired of the limitations (if you can believe that) and lack of effects. I'd been eyeing up a multifx for sometime and I don't remember exactly why I went for the A2S but I got one for £280 on eBay around the middle of this year which I think was a pretty good steal. I remember coming across some John Cordy videos, I liked what I heard and it seemed to be doing a similar thing to the HX Stomp (being my coveted multifx pedal) but alas was/is still too pricey for me to justify.
I love an underdog as well.
Anyway, it was really intriguing reading your opinions of the "Amp modelling" and responses to controls. Especially Amp Volume channel and breakup or lack there of. I can't remember where I read this, probably on socials somewhere but someone made a comment which really resonated with me and with what I've been experiencing. Hotone may have disguised this as an Amp modeler when in fact the amp models are (I believe) in fact profiles or captures. I've noticed sweet spots to every "Amp" model in the way that it will sound good at certain volumes or EQ , which is probably where it was captured at. It also makes sense that they have just released 'Tone Catch', possibly playing to their strengths in this area.
Not that it is a bad thing, everything I have heard online re: Tone Catch has sounded really good. Hotone have been great at communicating the delay with the A2S firmware. I think they have pivoted to competing with Tonex more than Line 6.
Agree with the summary of effects, just wish there were more. Maybe now their R&D has released Tone Catch they will focus on this aspect. I would love to see the same level of commitment to this range (as Line 6) before they decide to release a next gen version, the fact they are expanding the Ampero II line up is a good thing.
Last point from my experiences, I do own a HX One. I use this for drives/wah and it pairs so well. I know I should probably sell both and get a HX Stomp (especially with 3.80) but I'm keen to see what else develops for this pedal. Let's just say I really like what I've seen/heard so far and I'm going to continue to support Hotone. Its just the drives on this pedal are not the best, they subtract from an overall great experience.
By the way, theres a lot of love for the Fender Super at the moment. Try the 09. Black Super model/profile (Volume 47/Output 50/Bass 43/Middle 40/Treble 50/Bright On) paired with Heir Apparent. Love it.
