I purchased this case to go along with the Multiac SA Spectrum guitar thinking that the only difference between the Multiac SA and the Multiac SA Spectrum was the addition of the Seymour Duncan Lipstick pickup, but much to my chagrin the dimensions are such that the Spectrum will not even come close to fitting in this case. This case seems to be made for an electric and I wonder if the Multiac SA would fit either, being billed as an electric-acoustic, so do more research than I did. Overall a good case however, it's a shame I can't use it.
