Greetings and love brother!
guitar and as of a few years ago reggae are a huge part of my life, and im stoked to hear theres fellow reggae musicians on here!
i use to play strictly metal and classic rock for several years, and reggae is so different in the core of what it is that it can be super hard to approach as a musician, and i totally feel your pain! i went from being able to shred ozzy osbourne to barely being able to finish a basic song without messing up because its such a different expression of the guitar, its a melodic drum extension instead of a more standalone separate instrument like western music.
Heres some videos that helped me IMMENSELY in figuring out the different techniques. if you have any more questions after watching them, feel free to ask!
Blessings and prosperity!
