After retiring his Rickenbacker 4001 Burton used a number of high-end basses.

Among these was a Black Alembic Spoiler Bass he bought and used breifly in about 1983-1985, This bass probably wasn’t used on the recording of the "Ride The Lightning" album.

This bass was later stolen around 1984-1985.

This bass has never been found, so if you or someone you know owns a Black '83-'85 Spoiler be sure to look for a large chip in the back finish up around the side of the Peghead as it might have belonged to Burton.

Prince played an Alembic Spoiler bass live and in the studio in the mid to late 1980s. source The photo is of Prince playing Brownmark's Alembic during the Purple Rain tour.

Jason used an Alembic Spoiler from 1989 up until he switched to Sadowsky in 1996-97. I believe he used one during the San Diego 1992 show from Live Sh*it: Binge & Purge, and it is featured prominently throughout the show and during his bass solo. I do not believe he used one for studio work.

In this photo, we can see Steele playing an Alembic Spoiler Bass and was used for many of carnivores albums recording ,live shows and a in some type o live shows decked out in all black with green tape over the pickups classic Pete haha,

Pete has most likely had multiple ALEMBICS throughout the years,a birch top ,a burl top ,a bubinga top which you see on the live videos up ,all black(which was most likely one of his other ALEMBICS repainted), some of these are photos you can find out there in a weird sketchy photo album I had to sign up for

Other photos of this Bass can be seen here, here and here.
