A bronze-plated Demeter TRM-1 Tremulator Tremolo Pedal is used in Jack White's 'bronze' pedalboard for the Raconteurs. The pedal was mentioned in the 2019 Premier Guitar interview.

David Gilmour used the Demeter Amplification TRM-1 Tremulator during the 1993 recording sessions at Olympic Studios, as confirmed by Bjorn on Gilmourish, the largest David Gilmour tone resource on the net.

This detailed gear diagram of Jonny Greenwood's 1997 Radiohead stage setup includes a Demeter TRM-1.

The Demeter Tremulator can be heard in use on The Strokes' track "Juicebox."

On frontman.cz, in an overview of Tom Petty’s Mojo Tour rig, one of his pedalboards has a Demeter TRM-1 Tremulator before his gain stages.

Used in his Metal Machine Trio tour, seen most clearly (with red knobs!) at the 2:02 mark of the video, at the bottom of the image.

Nels Cline's use of a Demeter TRM-1 Tremulator was listed, photographed, and detailed quite extensively on a now-defunct website/gear journal Cline maintained himself in the 2000s (last viewed around Fall 2008).

If I recall correctly, Nels Cline explained how it was rarely used on his touring pedalboard by the time of Sky Blue Sky, but was still used in the studio. On tour it had been bumped from primary tremolo duty by a Fulltone Deja Vibe.

Now that Cline's old website is gone, the only reference I can find of him using the Tremulator outside of this random pedalboard picture from 2005, is his remaining inclusion in the wikipedia article for the TRM-1 and a few mentions in old messageboard threads, but no direct sources seem to exist anymore.

EDIT: Found direct source in a March 2005 issue of Guitar Player magazine, featuring Nels Cline on the cover. Nels directly states his use of the Demeter Tremulator on page 54 (highlighted in picture), and is pictured with the Tremulator in the bottom left corner of his pedalboard on page 60.

The Demeter TRM-1 Tremulator Tremolo Pedal can be seen in the center of the top row of Alex Trimble's pedalboard

"Above it is one of my oldest and trustiest tremolo pedals, the Demeter Tremulator, which was originally built for Ry Cooder to emulate the Fender Tremolo. I love it."

"I have often been asked how I got involved in the guitar pedal business. In 1982 Ry Cooder came to me asking if I could make him a tremolo pedal, as none were being made at the time. After some experimentation, and Ry's old Fender twin amp as a sound model, the Tremulator was born."

In this photo, which shows McIntosh's pedalboard (the uploader of the photo is an American guitar amplifier manufacturer Jackson Ampworks, which endorses McIntosh), one of the pedals that can be seen in his pedalboard is the Demeter TRM-1 tremolo.

In his YouTube video titled "The Gear I Use," samuraiguitarist features the Demeter TRM-1 Tremulator among his collection of guitar pedals.
