I guess I’m late to the discussion.

The problem that you will have (may have already encountered) is that Andy Timmons has his two chained together in parallel.

Pardon the cryptic flow-chart. To run dual delays like Timmons…

send
……………………. delay 1 dry out—> delay 2 in– delay 2 effect out –>return -]

Then you have to mix the two separately effected signals to go into the return of your effects loop.

Timmons is using a GCX (mixer/router), so it isn’t a big deal for him. If you’re just wanting to use a few pedals… it’s a different story.
