1958 Martin D-28

The 1958 Martin D-28 is an acoustic guitar made by C.F. Martin & Co. originally developed in the early 1930s. The guitar itself was designed to have a dreadnought-shaped body (the 'dreadnought' term referring to its large size) different to most small-bodied acoustic guitars at the time, but would go on to be one of the most popular acoustic guitars for its projection and tone.

Andy Summers wrote lots of songs on this guitar in the 1980s. He later sold it, to his regret.

He had the guitar with him for the sessions for Synchronicity at AIR Studios in Montserrat, but it's not very likely he used it on the record as it was more of a writing tool.

Quotes on the D-28
"'At one point I had so many guitars, I just needed to let some go. No idea why that had to include the D-28! Though I actually have another D-28 - it’s not even Custom Shop; it’s what they call an Authentic Series reproduction of a 1945 D-28. And it’s a fantastic guitar. I think it needs to be played for another 25 years to really get to where it could go, but it’s amazing already. Authentic is one more than Custom Shop: everything is cut by hand. They use animal glue, not synthetic glue, which makes a huge difference - you’d be surprised how much of a part glue can play. I have one of the few ever made.”"
