Adam T. Siska

Sisky played this bass on MTV Live in 2007, and it can be seen at :34.

At about 6 seconds into the video, you can see Sisky playing the Pete Wentz signature Fender Squier Precision Bass. There are plenty of pictures over the summer of 2008 where he was seen using the bass during warped tour. This clip was from July of 2008 at Warped in Scranton, Pennsylvania. His doesn't have the same insignia in the corner, but otherwise, it is still the Pete Wentz Signature.
