Matching resistors for phase 90?

I'm about to finish phase 90 build. I got 5% carbon film resistors by mistake so I'd like to know if it's crucial to match those resistors around fets (22K are the closest ones), since fets need to be matched. I should have asked this question before soldering those resistors, but better late than never.
Thanks

Don't worry about it. The JFETs have a far wider range than the resistors, and that's why they need matching.

In response to the questions in the forum - PCB Layout for Musical Effects is available from The Book Patch. Search "PCB Layout" and it ought to appear.

Yeah, and the caps are sure to be 5% or worse as well, so I don't think the 5% resistors will be noticed.
