I didn't bond with it at all, I found there was too much modulation for a lot of the modes I liked and that the repeats didn't blend well with the dry tone. Some seemed to sound like there was some reverb mixed into the delayed signal? I'm not sure but something about it was weird for me and I wound up only only using the user-generated slots. I much prefer the regular Flashback.
A lot of people like it though, if you like how the demos sound and are okay with having the modulation on the more intense side of things then go for it. That's a good price considering how much stuff is in there.
I love the AEx4, lots of great sounds for not a lot of money. Yes, most of the modes have a large dose of modulation, but you also get 4 toneprint slots that you can load up with clean delays or whatever you like (I tailored a 2290 algo for this purpose). On top of that you get the nice parallel .8th dual delay mode which I find useful. All in all not a bad deal!
I'm thinking about finally jumping on one of these after coming up with some Christmas $$. I own the Flashback x4 and love it, but I really like the AE exclusive pre-sets. I'll probably just change between the two since I already have the same board space mapped out for the Flashback x4.
I just got my yesterday. I'd been looking at the Flashback for awhile and when I saw the Alter Ego for $150 I pulled the trigger. Just started looking at the options with the TonePrint Editor and I can see myself falling into the rabbit hole of tweaking everything.
I actually came to the forum today to see if there are any discussions about using the TonePrint Editor.
