Curious to hear what you didn't like on it and what you moved on to. Was thinking about the Boss for the same reason but the people on this thread disabused me of that. I was originally gravitating towards a Polymoon (see what I did there?) but ultimately decided the H9 is where my heart is at for special effects and I could see setting it free from "everyday" reverb duties so it could shine in that role.
I have an Aftershock so I know the Neuro app. I kind of hate it for the Aftershock, though the basic sounds are already great (I use a cab sim in the effects loop to make it a sort of guitar amp distortion). I'm not sure I deserve that many parameters for distortion as I mostly make it sound worse when I edit it. But reverb is a different thing and I'm used to tweaking it in DAWs and on the H9 with good results.
well, i didn't disabuse you, i keep touting the 500 series' benefits. anywho . ..
this is all based on recalling gear from two years ago.
have an avalanche run that did the exp thing with reverb morphing/blend control, etc. i liked the idea, but i thought was weak.
i started exploring for more stereo delat and reverb pedals with exp pedal functionality.
so i got the ventris and the nemesis. i liked the size and the functionality. the ventris sold me on the two reverbs at once thing. the fact that the nemesis didn't have it started to bother me. i wrote source audio to see if they were gonna to a similar thing for modulation. they weren't. concurrently i had started looking around again. found the bosss 500 series and that seemed to fit the bill and has worked better for me.
sa stuff sounds goo, but the programming is not as easy as the boos stuff. it might be deeper, but the interface is such a pita that it cancels out.
i'm enough of a fanboi that i'd like boss to do a pitch shift and od/fuzz/bit crush 500-series pedals with the same architecture. (the od-200 doesn't do that from what i can tell.)
the boss has more accessible programs—both in terms of editing and getting to them in performance—and has some nifty ways to copy or swap programs.
iirc, the ventris didn't have a reverse reverb that really i liked. the rv-500 models the reverse (and other stuff) from the srv-2000, which i really liked.
it's easier to program the exp on the boss with precision (enter values in the menu, rather than tweak knobs on the ventris—i guess neuro helps you do that).
didn't love neuro.
the sa stuff has more parameters that can be accessed simultaneously by the exp pedal. i don't remember if you can make the tap switch into a momentary switch on the nemesis/ventris. you can do that on the boss stuff, which is something i use all the time.
i don't use it, but the rv-500 also has some delay before the reverb in a few algorithms.
the dd-500 models some of the sde-3000 stuff, which i think was a great delay. it also can get shorter times than the nemesis (iirc).
i like having these pedals with the same architecture—helps me keep track of stuff in live situations.
