Martin D-35E Retro. Chris Martin's vision for the Retro Series is to perfectly capture the mystique and tonal emotion of priceless, pristine and well-aged Martin guitars. With electronic imaging contributed from a 1967 vintage D-35 "donor" guitar, the resulting acoustic as well as amplified tone is projective, balanced and resonant. Classic and enhanced D-35 appointments include a three-piece back, black pickguard, ivoroid bindings and a certified European spruce soundboard with thin 1/4" width bracing. The visual appeal of the original D-35 is captured and blended with a High Performance Neck® taper for easy action and enhanced playability.
