I used to own a '79 Music Man Cutlass that belonged to Cliff Williams (AC/DC). It was bad, and all black!!

It was just one of the many basses I sold during my divorce :bawl:

The bass can be seen here.

In this video from AmpegTV, Cliff talks about his use of the Ampeg brand. In the description of the video Ampeg writes "Bass Frontiers Magazine recently sat down with Ampeg endorser Cliff Williams of AC/DC. Cliff has been a long time supporter of Ampeg and plays an SVT-4PRO with an SVT-810E cabinet.

All the cabs behind the band all seem to be Mesa Boogie cabinets

You can see his bass at 0:32 of the video.

He uses this bass on the whole Flick the Switch album.

[EDIT] HE OWNS THE BASS VERSION NOT THE GUITAR VERSION!!!
