MXR Noise gate IC help...

[jaki54321]

I am building an MXR noise gate from the board on Tonepad.com

It says in the PDF that I need an IC-4558 or a TL072. I was looking for the 4558 on small bear electronics and all i found was one called "IC JRC4558L" Is that the one(Hence the 4558 in it)? I found the TL072 jus fine with the name "IC TL072" Which seems pretty obvious that its the correct one, is it?

And if both of these are correct, which one will be better to use?

Thank you!

Yes, that's a fine 4558.

In a noise gate, either the '558 or the '072 will be fine. Both are fine small-signal guitar amps.
