I just want to mention that if you are thinking of going to Kingston to see a recording studio, then you might want to skip the trip and just go to the one in Negril.
I worked in the Reggae music business for many years (actually still do some work for them) and none of the big name studios in Kingston are open to the public, including the one at 56 Hope Road.
If you visit the Bob Marley museum the tour takes you through his house and the property but it does not (at least usually) take you in the studio because it is an active studio so many times someone will be recording, and even if not, studio time costs money which is why it is not likely to find a tour of an active studio.
Tuff Gong Studio is the real one you would want to see, but again, it is not open to the public as it is an active studio and most of the time it is in use. So you will only be able to get into Tuff Gong if you rent studio time or maybe if you know someone.
But I have some great pictures of both if I can dig them up I can post them....of course I know that is not the same.

I am also not saying dont go to Kingston, it is a wonderful place in its own right for many reasons, but if seeing a recording studio was your main or only objective to making that trip, I just thought I would mention it.
