Jacob Hurley

In this photo, Jacob Hurley can be seen using an Epiphone ET-290 Crestwood with a Cherry Sunburst finish. The guitar has been modified to have open-coil humbuckers and different knobs.

The ET-275 is similar, but has different fretboard markings and doesn't come in the same finish.

In this photo, Jacob Hurley can be seen using an Ibanez AX7221, custom decals on it to resemble the look of a hollow-body.

This guitar likely belonged to Bora Karaca, as in the video "What is Cojum Dip?" (youtu.be/uTM1VlFuQ3E), at 4:27, Bora can be seen recording a guitar solo for the song Tap Tap Tap, where he ends up yelling into the pickups. The fact that there are two "skunk stripes" rather than a singular one confirm that the guitar is an AX7221, and not a similar looking Ibanez guitar.

In this photo, the Fender M-80 1x12 can be seen right behind Jacob.

In an early rendition of "What Is Cojum Dip?", Jacob Hurley can be seen using a Fender Blues Deluxe amp at the 11:46 mark. This amp was used in performances starting at some point after October 2005.

In a photo posted on Cojum Dip's Facebook, Jacob Hurley (left) can be seen using a Fender Stratocaster. 

In these two photos, Jacob Hurley can be seen using a modified G&L SC-2 from the 1980s. The bridge pickup has been replaced with an open coil humbucker and is oriented parallel to the bridge rather than at an angle. Additionally, a custom pickguard has been added to the guitar.

In this Cojum Dip photo from 2006, Jacob Hurley (portraying the character "Laurence") can be seen utilizing the Seymour Duncan JB Model pickups on his Epiphone ET-290. The "Seymour Duncan" word mark can be seen on both the neck and the bridge of the guitar.

In this photo, Jacob Hurley (portraying "Laurence" in Cojum Dip) can be seen using a Black & Decker CD142S Power Drill. He would use this during the song Puzzle Dust.
