roland 4558 op amp data.

[ElmacacoX at aol.com]

Hi,

it's me tring to see why the congas don't work on my cr8000,  and I am trying 
to find the datasheet on the op amp IC marked 4558DD JRC 2424.  I've tried 
searching with google, but no luck.  there are many 4558's in my sh-2 as 
well, so it's a pretty common roland chip I imagine.

anyone have this?

thanks

Ed
