Pictured are soon-to-be newlyweds Ashlee Simpson and and Pete Wentz receiving early a wedding/house-warming gift from Travis Barker -- his sold-out Ghettoblaster Boombox thing-thang.

The damned thing is not just sold out, but going for $600 on eBay.

The tattooed rocker held a release party just over a week ago in Los Angeles at Central Hollywood with DJ Spider. Two days after the event the i931 Ghettoblaster sold out at Barker’s boutique store in California. Barker personally sent a few of the only 400 music players to artists like Rick Ross and Pharrell Williams, as well as The Game.

The former Blink-182 drummer is also set to work on a track by the Compton rapper. Barker has been working on a remix to The Game’s street single “Big Dreams,” produced by Cool & Dre. The drummer had success earlier this year remixing Flo Rida’s hit “Low” and in the past re-twisting successful hits by Pharrell and Rihanna.

Barker is currently working on producing tracks for Paul Wall and is mulling over the idea of compilation-styled solo album.
