Stacked delay and dual delay setups don't have to be complicated to sound great. These are my favourite simple and easy dual delay setups that I use from time to time.

Timecodes:
00:00 - Intro
00:30 - 1. Short Reverb like Delay + Long Delay
02:20 - 2. Easy Classic Rhythmic Dual Delay
04:22 - 3. Contrasting Sounds & Using Different Rhythms
06:15 - 4. Ambient Wash Using Multiple Delays
07:52 - 5. Using Two Delay Pedals for a Single 'Custom' Delay Sound
