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 Alvaro to never miss gear updates.
At 0:48 of this video from Spinnin' Records, a close up shot of the 12sHO's can be seen.

The source and notes on this submission are correct.
