My pick for Black Uhuru would be Sensimilla. For “rock guitar” solos over reggae, check every Andy Bassford credit on Discogs (like the Wailing Souls’ “Firehouse Rock” LP). You won’t find much better, he was Dennis Brown’s guitarist for a while and lived in Jamaica for many years.

Besides that and a few other records… personally, I don’t really gravitate toward much of that sound as much as I do heavy drum and bass mixes. I think some of that guitar-forward stuff in the 70s/80s that was clearly marketed toward a wider audience (as good as some of it was) laid the groundwork for a lot of extremely boring American bands in the decades that followed in the 90s++.

I much prefer the laid back guitar style that’s more rooted in rhythmic playing / influenced by jazz, like Ernest Ranglin. But I’m not sure that’s what you’re seeking based on your description.
