I thought the house bassist uses Silver Slaps.
A double bass is such a classic instrument that it can open a lot of doors. I'm not very good bassist and I never make any attempt to network; still, I get offered more gigs than I can take on, so I end up declining some quite nice ones (and well-paid too, & some abroad stuff). This is because the bandleaders want a double bass rather than EUB or bass guitar. The style is jazz, swing, rock'n'roll, "postmodern jukebox". (Not intending to discourage anyone from taking up EUB - just giving a perspective.)
