Five Finger Death Punch are rocking out all summer long on the Mayhem Festival, and bassist Chris Kael is enjoying the opportunity to put his stamp on his new CK-4 signature model Spector bass guitar.

The instrument features neck-thru body construction with carbon fiber reinforced three-piece rock maple. The rosewood fingerboard comes designed with 24 frets. Alongside the solid maple body wings is the EMG BT Tone Circuit and EMG P/J active pickups.

Kael says, "Having played Spector long before joining Five Finger Death Punch, I am extremely happy to now be in a position to collaborate with them on the design of the new Chris Kael CK-4 Signature Model. Combining the playability and feel of Spector with the tone of the EMG P/J pickups and the attitude of the brass knuckle bridge, this is the bass I've always wanted. One man, one beard, one bass. Spector, son."

The CK-4 model will be available in matte black or matte white with black hardware, with a "Knuckle-Head" brass knuckle plate in black designed for the white model and in chrome for the black model. For a closer look and additional specs on the CK-4 signature model Spector bass, check here.
