Does anyone know if a 2N5089 is a good replacement for the 2SC1815 in a tube screamer build?

Should work fine. The two transistors are used as emitter followers; in this configuration most small signal NPN transistors should work OK if not great. 5089 will be great.

Get the pinout right! The pins are in different order on the 2N5089 from the 1815. The 5089 is EBC, the 1815 is ECB.

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.

yes, 2N5089 or BC550 works fine  ;)

Would there be an audible difference?

No. Probably not with any NPN silicon with a gain over 200.
