In some ways, it’s hard to know whether to categorize the Martin D Jr E StreetLegend as a backpack or travel guitar. After all, Martin still maintains the LX Little Martin line, which is marketed in very specific terms as a travel instrument. And the D Jr E’s size, which isn’t a whole lot smaller than my Martin 00-15, stretches the boundaries of that classification. But Martin definitely leans into the go-anywhere appeal of the D Jr E and its brethren in the new revamped Junior Series. If the soft case fits, wear it. Assuming it lives, at least partly, in that category, it is among the best sounding travel guitars I’ve ever played. Thanks to the all-solid spruce and sapele body construction, it possesses a warm, woody, and organic voice that is likely made richer by the new, longer 24.9" scale.
