"Captain" Kirk Douglas uses a Dunlop Jimi Hendrix JH1 Wah on his live pedalboard rig for The Tonight Show Staring Jimmy Fallon. It is shown [@ 2:30] in the video. When asked why he uses it, Kirk replied, "It's got a nice sweep and it has Jimi's signature on it."
This photo of Jordan Cook's pedalboard was taken at his performance at the Surrey Fusion Festival 2011. The 2nd pedal from the left with the "Jimi Hendrix" label is the Dunlop Jimi Hendrix Wah-Wah Effects Pedal.
