I really want to make an acoustic dub, or electric, I don't really care, but i don't really know where to start in terms of chords to use. I am familiar with this style of music as well as similar styles so I don't need band recommendations, but maybe some good videos or tips. Help would be much appreciated, Thanks!
Listen to Bob Marley, change song titles, sing undecipherable lyrics in a jamaican accent. You win.

Invest in a tape echo machine and a spring reverb. Or get really good VST emulations of them.

Usually, reggae doesn't have more than two or three chords. Since dub is basically remixed reggae, it's the same way.
^Absolutely nothing to do with this thread, but getting lost in the supermarket as a little kid and not being able to find my mom was one of the worst feelings I remember from that time of my childhood.
