Maxon OD820 IC Question

[Meomy]

Newbie question here.....
I'm using the layout below and wanted to know how dramatic a change in the sound it would make if i substituted the JRC4558 IC for a NJM4558.



I've got a bunch of NJM4558s, but don't have a JRC4558 on hand and want to build this one ASAP and still have is sound great.

I bet you won't hear the slighest difference, even if you put any dual opamp except a 1458, so use what you've got, no problem.

Thanks JaviCAP
I'm REALLY excited for this build!
I've seen some cool demos and heard nothing but good things about this one.

Yeah, this is a really nice sounding pedal.

And taking in mind that I hate overdrives, to reckon that I like this one very much is maybe the best praise I can do :P
