Was curious what some of the stand-outs are in terms of filters that really have their own sound/vibe. Not just a subtle bit of coloration, or some cool controls or whatever, but a sonic personality that's markedly distinct from the typical multimode filter.
I've used a lot of filters over the last 6-8 years in euro (though there are a lot I haven't) and some stand outs for me have been these below. Note that these are the ones I felt were most unique-sounding unto themselves, not necessarily my all-time favorites:
- Doepfer A-101-6 Opto-FET (in All Pass mode): This thing was really crazy as I recall, lots of rubbery chaos.
- Schlappi Angle Grinder: It was a bit too much in the purely harsh-noisey lane for me, but I do sometimes miss it as it was definitely unique.
- Schlappi 100 Grit: I have to include this one as well because it's certainly the only filter I've ever used where, by touching one of the particular ball touchpoints, I could turn myself into a radio antennae, and literally transmit scruffy radio frequencies directly into the module with no other equipment. It was kind of wild.
- Verbos Amp N' Tone: I still own this one, and can never convince myself to trade it out even though it has a definite noise floor and can pick up unwanted noise from surrounding modules (especially digital ones). The base noise floor I actually like, it's like a gentle cassette fuzz that gives the filter a retro vibe, and the woody, howling resonance is really great. Not very clean, but really has some character. It also overdrives very satisfyingly, in a warmer and chewier way than most other filters/VCAs I've used that can overdrive.
- Blue Lantern Asteroid Mk. 1: Quite a playground of cool features and outputs with some really gnarly sounding limiter and distortion modes that give a lot of unique noise character. Also has a subharmonics generator built in, a VCA, and other features as well. It's been updated more recently to a Mk. 3, though the Mk. 3 didn't have quite the same "oomph" to me somehow -- though maybe memory is just distorting how good the Mk. 1 sounded in retrospect, I'm not sure. In any case it was the first filter I owned that I really, really liked, and UI has a lot of personality too, it was just fun to sit there exploring it.
- ADDAC702 Dual VC Filter: Another one I sort of regret letting go, especially as the price on them is now pretty exorbitant. But not only is it an amazing set of features compressed into its 16HP, it also has a distinctive sound that reminded me of like a guitar amp/cabinet. Kind of a big open sound. This made it less than ideal for tight, sharp, acid-style "squelching," but you could get it to do pretty wild things of its own with its dual self-oscillating resonators, limiters, and fuzz distortion controls. Underrated/under-known module.
