In early 2003 GPC released a Matt Skiba model guitar and a Dan Andriano model Bass guitar. The Matt Skiba model was limited to 200 units and the Dan Andriano model even less a mere 25. Any hope of a re-release seem dashed as GPC have recently gone out of business. Below are the specs for the two models so you can attempt to build your own.

Slightly happier news is that Derek Grant is releasing a signature drum kit more than likely from C&C Drums (see images above)
