I'll start by saying - this is *NOT* A STRAIGHT MS20 CLONE. To actually emulate the MS20 filter section you would need two of these patched in series - if you are purchasing for that MS20 sound bear that in mind, treat this as a completely different beast.
Now having said what this module isn't, I'll say what it is. Quirky, unusual, gnarly, crazy, raspy, openly-patchable, characterful - the list is endless. This is not a go-to bread and butter filter - take a look at the a106-5 sem filter if thats what you are after - but what it does, it does incredibly well. Balancing the input gain against the resonance and clipping levels can yield some incredible sounds - rasping brasses are a speciality for it. I also love using for drones as the deep lowpass with clipping is great when you patch out the resonance feedback path (I like using a189-1 vc bit mangler and a199 spring reverb on it). The filter responses are adjustable with trimmers on the board which is useful.
You wont find yourself using this on every patch, but it'll add so much to those weird and wonderful distorted sounds that you wont regret the investment.
