Korina is indeed Limba from Africa, and is related to mahogany.
Gibson and Hamer have made guitars of korina, but I've heard that Epiphone korina V/explorer aren't made of the real deal.
I have warmoth one-piece black limba hardtail jazzmaster with rosewood neck (no finish needed) and fingerboard. Unplugged it's loud and resonant, and with Mule set(A4) it sounds awesome! Very even, fat but clear,
great dynamics and sustain, and can really do anything from jazz to metal with right amp and attitude.
So: Probably the same as in mahogany. Maybe a tad brighter. +1
