I've been involved with the German Dancehall scene from around the late 90s early 2000s and danced so many nights to this riddim. I knew the story and how this riddim ended up in Jamaica at King Jammy's (e.g. https://www.youtube.com/watch?v=Mop89McbxAE ), but could not remember to have seen an image of the actual keyboard before.
Overall these riddims are played at so called soundsystem parties - basically huge amount of subwoofers that your body shakes. Earplugs is a must else you'll get tinitus like I did. Stranger part is no photos are allowed and a lot of music isn't released online - it's overall kinda secretive subculture.
It blew my mind when I came to such party first time.
Americans might best know it as the bassline from Sublime's Caress Me Down (https://www.youtube.com/watch?v=k_LP4IU6XD4).
But you might really love the lyrics of Tenor Saw's Pumpkin Belly, which a song of the "old time proverbs":
"Whatsover you want / You have to work very hard to gain."
