Electrolytic capacitors instead of film?

[xorophone]

Hello! I'm currently building the Leviathan delay from Etcher's Paradise but I realised I don't have any 1uF film caps. How can I use electrolytic capacitors, which are of course polarized, instead? Which way should they face? In this schematic the 1uF caps are C6, C7, C17 and C20.

Also, will it make a noticable difference in sound for example?

Thanks!

It's a similar setup as this.  Just compare the schematics.
You won't notice much difference IMO

The plus end on electrolytic caps always go toward the higher voltage source.
For C6, + goes to R8.
C7, + to pin1 of IC1
C17, + to R18
C20, + to R21

Thanks! Fast and great replies from both of you!
