Ibanez Musician MC-900DS fretless

The Ibanez Musician MC900 bass was one of Sting's most iconic basses, dating to the Reggatta De Blanc era (1979-1980). This is the first of the Ibanez basses Sting had.

Background
As it appears, Sting first used an Ibanez fretless bass on a RockPop TV performance filmed in May 1979.

It was previously thought he bought the bass from Summerfield’s Musical Instruments Dealer on 15 June 1979 (probably Sheffield) and then used it first on the "Can’t Stand Losing You" video. But it’s likely the Ibanez bass featured in the RockPop performance was a borrowed one and Sting bought one shortly afterward at Summerfield’s.

Eventually Sting would migrate to the Ibanez as his main bass from the Fender Precision fretless, following the completion of the Outlandos D'Amour tour in June.

Sting had played this bass on the Reggatta De Blanc album, recorded at Surrey Sound Studios in Summer 1979. As well as for much of the subsequent tour. In Spring 1980, the Ibanez had a rhinoceros sticker on it.

With regards to the model, many sources documented this as an Ibanez Musician MC940 fretless. But it appears to be a standard Ibanez Musician MC900 model albeit converted to a fretless.

A similar Ibanez bass (which wasn't Sting's but has a similar fretless neck) is currently owned by Fabio Trentini of The Police tribute band "The Ghost Machines".
