Okay so i will show you my setup and then i'll explain my confusion.

Amp-Blues Driver-TS10-TS808-Digital Delay-Guitar

Is this right? Because i've been seeing the amp and guitar thing and I don't know which side is which kinda thing. Like if i added a wah would it go to the left or right? Sorry if i'm not too clear.
Delay usually goes at the end of the chain before the amp, and do you really need 3 different ODs?

Wah would go straight after the guitar.
