Dunlop Cry Baby Wah pedal

Sting reportedly had a Dunlop Cry Baby wah-wah effects pedal during the 1970s, as discussed in a 1980 magazine interview. It was probably used during The Police's early days, but there's hardly any surviving photographic evidence for this. He eventually lost the Cry Baby, and replaced with an MXR Phase 90 instead.
