Some different wiring diagrams.
I can't see how anyone of these is "better". I normally use modern wiring with independent volume controls and find it ok.

I had a berigher phaser once. It was dirt cheap ?29 new!!!
It sounded nice, But it was noisy, felt cheap. It looked put together well just not good quality components.
I'd save up for something a bit better. Berhinger is very low end.
