Is it kosher to play Led Zeppelin tunes on a Steve Howe signature model guitar? Yes! James DePrato solos on “What Is and What Need to Never Be” and “Ramble On” with the assistance of this 1999 Martin 00-18SH. Patterned after Howe’s initial 1953 00-18, the guitar has a vintage vibe, thanks to its original-style rosette and inlays, sealed Kluson tuners, and tinted soundboard. The SH classification shows that this is a special design, with Howe’s signature inlaid at the 18th fret.
