MC4558CN in a TS?

[zombiwoof]

I ran across this version of the 4558 when I was looking at some components.  I know that subbing different 4558's or 4559's in a Tube Screamer or similar pedals can have subtle tonal results, and wondered if anyone had ever tried this one (which I don't recall anyone mentioning), made by ST Micro?.  How does it sound?  I can just buy some and try them when I socket my pedal, but though I'd ask.

Thanks,

I have some for me it sounds the same (well some days I imagine I can hear the difference heh).

I know that some say the JRC version sounds different than the Texas Instruments 4558, so I wondered how this one compares to those two.  I know it's a subtle thing, I guess I should just order some and see for myself.
