I liked the most detailed response that I got on this forum, which I felt made the most sense. Especially with the phrase, 'truly hollow body'.

But apparently, some do, which is why I even brought it up. If it wasn't built like an acoustic guitar (nothing in between), and had them, it was a semi-hollow. There were some responses on those that basically said, any block of wood or post between the front and back face of the guitar relegated the guitar to semi-hollow status. The question was also asked in several other forums that I frequented back then. Back when I first joined this forum, in 2010, I posed the question of a sound post being in my first Epiphone, a Casino. Somebody else wandered into pinned bridge territory. This: They call Casinos, Swingsters and Sorrentos hollow bodies, but I believe they have sound posts, which may disqualify themĪctually, no, that comment wasn't concerning pinned bridges, but sound posts. The comment came from a previous comment that seemed to question the whole aspect of a pinned bridge changed the terminology, I can't see why/how it could. Yep I know Red, I have a few Archtops with non pinned bridges, (Broadway/Emperor Regent/Elitist Country Gent all have floating bridges - the Country Gent however is a semi hollow with a center block.) Pinned bridges won't move during a string change.

During a string change, the bridge can shift out of position, making it harder to put back in the same place to maintain intonation. Non-pinned bridges are called floating bridges, and are held in position by string pressure alone. This is in contrast to the larger screw posts or comparitively massive stud and bushing assemblies on tunomatic type bridges (whch are also used on hollowbodies). It simply indicates that two small pins are used to locate the bridge to the guitar's top. A pinned bridge would not disquaify a guitar from being a hollow body.
