One musician who appreciated the Rover was David Gilmour. Since the early days of Pink Floyd, Gilmour used a Leslie 147 on “The Narrow Way” from 1969’s Ummagumma. For 1973’s Dark Side of the Moon, it’s variously reported that he used either a Maestro, Leslie 900, a Univox Uni-Vibe pedal – or perhaps all three. He then adopted Yamaha’s RA-200 rotating speaker, combined with his Hiwatt amps, for Animals in 1977 and The Wall in 1979, specifically on the solo in “Comfortably Numb.”

During sessions for 1994’s The Division Bell, Gilmour used the Maestro Rover. When the Floyd toured the album, he toted along three sets of custom rotating-speaker cabinets called Doppolas, built from Maestro Rovers by his techs, Phil Taylor and Paul Leader, and using a pair of similar rotating 6″ speakers with concert-worthy 100-watt drivers. Gilmour ran them in tandem with his stationary 4×12 speaker cabs.

On songs such as the instrumental “Marooned,” Gilmour’s prolific use of the vibrato, bent notes, and the whirling Rover combine to create an ethereal mood with echoes and waves of sound playing against each other.
