While poking around online for info on the Gibson neck "mud-buckers", I noticed something interesting (to me, anyway): both David Gilmour (of Pink Floyd) and Tony Visconti (who produced and played bass on the majority of David Bowie's albums) have "mud-buckers" installed on their main studio basses. This was one of Roger Waters' basses that had a hideous "psychedelic" paint job, which Gilmour stripped down and modified. Roger Waters is tone deaf, and Gilmour actually played most of the bass parts on Pink Floyd's albums from the '70s. The fact that he chose to have it included here at the Interstellar Exhibition in Paris, along with most of his guitar gear, says a lot. Tony Visconti's seems to have an early '70s Tele bass humbucker (along with several other pickups). God knows what all those knobs do. I wonder what the best position for the "mud-bucker" would be on a P-bass; I know that the best place for a humbucker or sustainer on a guitar is (top coil) directly on the 24th fret (I've done a bit of experimenting with this). Any thoughts? Anyone have a wiring schematic/diagram for adding one of these beasts?
