That looks good. Is this just the exact copy described earlier in the topic? Or does this differ from what has been discussed here?
Are you willing to share your experience and schematic? So that we can all learn something from it?

Thanks! Those are oryginal schematic with equivalent (TDA1022), and mod supply section.

Bingo!
I am honored to show you me newest project. It is a copy of iconic chorus BOSS CE-1. I spend months over this project,  of course I made lots of prototypes.
Here are differences between mine project and original:
👉power supply 9V or polarization BOSS
👉substitute hard to find analogue delay line MN3002 with newer electronic circuit
👉smaller box

My English isn't best, but... my new project
