(perhaps I’m about to write too much about erbe-verb in the mimeophon thread, but…)
Pretty much anytime I post something prominently featuring Erbe, I get comments from people very surprised at how lush it can sound. I personally find its reputation as a purely experimental metallic reverb to be somewhat overstated. But it wasn’t instant for me that I found the sweet spots I like. I wouldn’t even say I like the majority of spots. But on the spots I do like, no reverb I’ve used has better given a sense of the sound being immersed in the space as opposed to reverb being slapped on top.
There’s a lot of controls, which all have a major impact on the sound with even tiny tiny adjustments, so it just takes time and experience before your brain learns how all the controls behave, interact with each other, and what combination of parameters gives you the sound you’re looking for in that moment, especially with how much they DO affect each other. eventually, just like anything else, manipulating all the controls to get what you want becomes instinctive, quick, and easy. for some people it certainly may never give them what they’re looking for, we all make different music and like different things from our tools, but I love it.
I will say, for me there isn’t necessarily some particular amazing sexy thing about it. At the end of the day, a delay is a pretty simple thing, and in my experience the sonic difference between modern digital delays (when not trying to emulate tape) is not all that significant. I think the reason I enjoy it is the sum of its parts- the combination of features, big versatility with the color, modelessness, and just the tactile experience of using it. and of course it being in euro is a fun bonus for cv shenanigans, though truthfully for my use cases, I find myself rarely doing much else beyond urate modulation
