Ariana Grande uses a TC Electronic Reverb 6000 processor as part of her live performance setup, as confirmed by Meyer Sound. Both Francis and monitor engineer Justin Hoffman mix on DiGiCo SD7 digital consoles, while Grande sings through custom-decorated Sennheiser 5200 wireless microphones with MD 5235 capsules. Additional outboard gear includes the Rupert Neve 5045 primary source enhancer for the strings, with systems engineer Brett Stec overseeing the setup.

The TC Electronic Reverb 6000 can be seen the video at 2m52s, in the background, over the main console in the composer's studio.

”If I have time, the reverb I use most is the TC Electronic Reverb 6000, which I think is the best reverb ever in the universe".

Noel Hogan is associated with the TC Electronic Reverb 6000, as detailed in a Pinterest post by Jonathan B Diaz Hernandez showcasing Hogan's guitar rig setup.

Monitor engineer Jean Charles Ethier (left) is also manning a Studer Vista 5 (24 stereo mixes, 16 FX auxes), using such features as snapshots and the Contributes function to access the mix directly. His rack gear comprises SSL X Logic Series, four TC Electronic 6000s, Millennia preamps and a host of analog gear — no plug-ins to be found. Ethier has 16 reverb channels coming out of the 6000s, using them for the band effects, “as we are using in-ears,” he says, “one on the drum, one on percussions, two for guitar, two for keyboard, one on violin, one on acoustic guitar, one on piano, four for vocal, two guests and one for Celine [sic].”
