TAL-DUB is probably one of the best free vintage delay effect plugins out there. It has a beatuiful tone to it, and the resonance knob gives a nice vintage feel to your productions. Make sure not to overuse the resonance though, because it can get quite harsh.
You can also link parallel parameters to each other in order to make them sync up. This can be done with the delay time and feedback settings.
Check the video down below to hear it in action.
This delay can be used in any producting where you feel like your standard delay isn't enough or for an element that you want to stand out from the rest. I wouldn't use this on every element though, since it can easily get a bit too much.
