Hey there! Thanks for the question.

For this tutorial, I used my Line6 Pod-XT to dial in all the sounds.
Here are the settings I used:

Marshall JCM800 Model:
CLEAN: Drive: 50% Bass: 55% Mid: 70% Treble: 60% Presence: 75%
CRUNCH: Drive: 100% Bass: 75% Mid: 70% Treble: 50% Presence: 75%

DIGITAL DELAY: Time: 440ms Fdbck: 45% Wet/DryMix: 40%

REVERB: Medium Hall WetDryMix: 40%

For the echo, you can use any digital or analog delay or echo pedal or effect. The general idea is to dial in longer repeats, since it is a slow ballad (around 440 ms will give you 8th note repeats at this tempo).
