From a guitar POV, I’ve always liked Empress; I have some of their other effects.
In my limited experience patching in pedal format effects with Eurorack, I don’t like the messiness of various different cords, connectors, etc. I prefer something more systemic.
But…you’re making me reconsider a little. Maybe one Empress after all.
The big, CRUCIAL thing in its favor for end-of-chain effect is that it maintains an unaltered pure analog dry signal from beginning to end, which is what totally disqualifies the otherwise nice Eventide stuff, and whatever else forces my dry signal through an A/D/A chain. In effects loops/aux send-returns, they’re fine, but for pass-through, no way.
Strymon I believe uses the same routing; not sure though.
BAM I know not much about. Looks cool, but I don’t like the demos I’ve heard, but that’s more to do with how the users use them than the effects themselves. Personally, I find that 98.72% of the time, users drown their dry signals in too much reverb, with too long a decay, in too big a space.
But that’s just me.
Let’s discuss reverb theory!
As an aside, I finally tried the Aeverb Mk ii/ADM21 yesterday, and was surprised by how disappointed I was in it.
But…maybe I shouldn’t have been, as it’s exactly what I always disliked twenty+ years ago in the Alesis stuff. I get that people like that sort-of retro/character sound, but for my purposes here, it’s a non-starter.
I do have high hopes for the ADM23 though as a kind of master bus effects unit.
