help with foxx tone machine caps polarity orientation

[kymar]

Can anyone tell me correct polarity orientation of this 10 uF electrolytic caps numbered in GGG schematics as C4, C5, C7, C12 ?

In fuzzcentral schema С7, С12 have vice versa polarity, and in Fulltone ultimate octavia schema C4, C5, C7, C12 stay vice versa, which is correct?
Or post some HQ gutshots 

Thanks

the GGG layout is correct

the + side of each electrolytic should always point towards the higher voltage (- side to the lesser)
