Although I still haven’t seen SkyFall, the new James Bond flick, I did have the MI-5 to keep me company. No, none of the UK’s deadliest spies were here to assassinate me. I'm talking about the MI-5, Musicvox’s latest 12-string electric guitar, curiously named after Britain’s internal cloak-and-dagger intelligence agency. I can safely say the only thing undercover about this guitar is how its 12 tuners are slyly arranged on its headstock.
