Here's a link to a new band called Walking Papers. Awesome, organic sounding rock and roll at it's finest. Plus, Barrett Martin is in the band so you know the drumming is tight. Anyway, what kind of bass is Duff playing? Looks to be some sort of hybrid P/J thing. Jazz body, P/J pickups. Geddy style neck with block inlays on maple fretboard. Custom shop maybe? There is a good close up of the body and neck at the 3:50 mark at the end of the video. Earlier in the video I can see "Fender Jazz Bass" on the headstock.
