FETISH is “solid” brother of OSS. There’s a sidechain filters like OSS. Plus, you can “SLAM” it! SLAM function is well known mod in DIY world. On the original gear, when pushing all “ratio”-buttons at once, you’d get a wrong bias and threshold. SLAM mode fixes this issue and adds more character.
The filters will shape your compressor sidechain. Control low freqs, mid freqs. High Freq will control your high freq sensitivity and tame it. FETISH is all about delivering that classic sound, without the classic’s limitations. Another extra feaure is MIX. Now, you can mix your compressed and uncompressed sound!
