Chandler TG2

At 1.03 of this video from the Lonerism Episodes, a Chandler TG2 can be seen in Kevin's rack.

Kurstin recorded Sia’s vocals through his Telefunken ELA M 251 into a Chandler TG2, through a Fairchild compressor and into the Apogee Symphony, they only needed minimal processing through a combination of Logic channel EQ, Waves’ CLA-2A compressor and the Lexicon Hall reverb. This was the same vocal chain that he used on his mix of Burn the Pages.

At 1:13 in the video you can see his TG2 Below his 1176 Compressor

Sitting on the desk along with some keyboards!

According to the "equipment list" found on Church Studios, owned by Epworth, one of the things listed is the Chandler TG2.
