Honestly, not really. The erbe-verb is very clear and has something metallic (not in a bad way imo) about it and the mimeophon seems like its darker sibling. I know that a lot of people use the halo on the mimeophon as a reverb but, to my ears, it’s very different from the erbe-verb.
My use case for the erbe-verb is usually giving space to sparser, high-register voices to make them last and ring out, which it does quite well. I often couple this with rythmically triggered long envelopes modulating the size, which adds a bit of structure.
The mimeophon usually acts as a straightforward delay that I heavily modulate using the voltage block to give me lots of character for whatever I run through. It’s also a wonderful chorus-like enhancer for everything from bass sounds to samples and a phenomenally unstable synth voice (so much so that I’ve contemplated getting another).
Both also warble quite well! If you like tape-like vibrato stuff, both do it in their own, interesting ways.
In writing this, I kind of realised that they are probably my favourite modules. They are endlessly playable, the whole modeless idea really works for me and I don’t think I’ll ever get sick of their sound. Together with QPAS, a morphagene and some modulation, I think I’d be quite happy.
(Make Noise isn’t paying me, I swear. Although, for another mimeophon, I’d sing their praises all day!)
//edit: Just to add, depending on how much you want to spend, the FX aid seems to have great reverbs as well, I don’t think you can make a wrong choice here.
