LJMC is a solid mahogany Large Jumbo model, same appointments exactly as the SJRS with the armrest Paduak feature and Florentine cutaway but using Mahogany for the back and sides instead of Rosewood and Cedar for the top instead of Spruce ,also ther body size is wider and deeeper giving it an overall deeper, softer sound. Still has the Gotoh machines, one piece mahogany neck, ebony fingerboard. It is an absolute joy to play, with the same easy action as all Terry Pack guitars.
