Alex B has awesome Vintage Synth Filters and Vinyl libraries.. vinyl is not a filter library but there are two vinyl presets that sound very lo fi and very natural at the same time Eric has some nice filters too.. and oldschool samplers textures
Thanks guys for the replies. I actually have used the wollensack for this purpose on some strings before. I also purchased the vinalyzer from alexb a couple weeks back. I was looking more for a filter type thing.
