S-5

 This is my jumbo model, and also my 12 string guitar.

 I've played around with the design over the years, particularly changing the ratio of the widest point and narrowest point on the body. Eventually settling on this configuration as the sound I like best for it. A decent lot of large body sustain and bass, without getting too flabby and boomy, especially in lower tunings.

 Width at upper bout - 305mm

Width at waist - 260mm

Width at lower bout - 430mm

Body length - 520mm

Scale length - 645mm
