Yeah lot’s of delays will get sold once this is out (except maybe the small ones, which still have an edge maybe). Many big-panel delays look kind of shabby now compared to this.
Talking about 4ms, I think the Topographic Delay still might be interesting due to its very peculiar approach to multi-tap, though of course it lacks some of the extra power of the Magneto (sound-on-sound looper).
For me personally this is very interesting, I can see myself using the looper mode a lot, especially since it does have an external feedback loop and works with 4 virtual tape heads which opens it up to all sorts of interesting manipulations, but I’ll have to study it a bit more of course.
