Hello,
i'm asking about the sunking build, I need for C15 a 3n9 capacitor
is it ok if i use 390pf silver mica instead ?
i can't source that part, not at mouser/smallbear/pedalparts
No, you need a 3n9 cap. That's 3900pf. I might some, but I got mine at smallbear so...

You can put two 2n2 caps in parallel. With tolerances factoring in, it will comes out to around 4n2 or 4n3. This cap determines the treble response in the tone control, btw.
Smallbear does have them: http://www.smallbearelec.com/Detail.bok?no=162
