Jackson Y2KV Dave Mustaine signature
The Jackson Y2KV Dave Mustaine signature guitar was introduced in 2000 (see above for a scan from the 2000 Jackson catalogue). 2002 catalogue scan can be viewed here. The first production run of 32 Y2KVs was started in January 2000. These were assembled between March and August. 80 more were started in September 2000 and 33 more in December. Most likely another circa 150 of them were built before the series was discontinued in 2002.
Dave Mustaine had a truckload of Y2KVs. He received 10 of the initial batch of 32 and most likely got another 15 or so later on. He also had many custom shop Y2KVs including the prototypes. Dave has sold most of his Y2KVs - first through Andy Brauer and then later on Ebay. Some of them were also given to his friends.
During the Andy Brauer auctions in May 2002 Dave sold practically all the production Y2KVs that he got from the first patch. Below is a group picture of the auctioned guitars.
The white Y2KV serial U07869 was recently seen on Ebay. The silver Y2KV with a matching headstock can be seen with it's owner here.
When Dave's contract with Jackson came to an end he got a large number of Y2KVs. These have high serial numbers and they were sold during the Ebay auctions:
Jackson Y2KV trans red mahogany U09324
Jackson Y2KV black metallic U09559
Jackson Y2KV charcoal metallic U11911
Jackson Y2KV mahogany U11921

Jackson Custom Shop Y2KVs
Below are pics of J6612, the only 12-string Y2KV ever built, and J6648 which has a Floyd Rose bridge and a silver sparkle finish. Both of these guitars are still with Dave and for sale on Megadeth's official website. These two are the only Custom Y2KVs I know of that were built for Dave after the initial prototypes.
Jackson Doubleneck Y2KV
Jackson also built Dave one doubleneck Y2KV. It was sold through Andy Brauer and can be seen on current owner's website. This one is possibly one of the largest Jackson guitars ever built.
