Equipboard's gear archive is collaboratively built and maintained by fellow music lovers like yourself. Anyone can submit gear and equipment to artists. Joining Equipboard also allows you to create your own list to track the gear you have and want, and follow artists like Pat O'Brien to never miss gear updates.
Pat can be seen here posing next to his rig which includes Triple Rectifier heads. They have been used on every album since 1999's Bloodthirst. They can be seen being used for tracking guitars on the making of Evisceration Plague in this video https://www.youtube.com/watch?annotation_id=annotation_395924&feature=iv&src_vid=sDQrZgsiM6Y&v=OrWI-aOyxew
