Daft Punk

In this article on a Daft Punk fan site, it says that the duo used a Boss MT-2 Guitar Pedal with a Juno 106 synth to create the sounds heard on their song "Rollin' And Scratchin'"

Daft Punk is widely reported to have used the DigiTech X-Series Bass Synth Wah throughout their album "Human After All." While the YouTube demo by g3zar highlights the pedal's capabilities, it notably resembles the sounds prevalent in Daft Punk's work.

Used on Discovery, as stated in this May 1, 2001 Remix interview.

You use vocoders and phase shifters on many of your tracks.

Bangalter: People always ask us what vocoder we use, but every one of our vocal tracks uses a different vocoder effect. We have the old Roland one [an SVC-350], Auto-Tune, and a Digitech Vocalist. We take the same approach with phase shifters. Every track on this album uses a different phase shifter. We have a Mu-Tron phaser, a Moogerfooger pedal, an old AMS phaser, and an Ensoniq DP-4. With the older items, you can have several of the same model and they all sound different.

The photo from Partyscene shows Daft Punk using a Boss PSM-5 Power Supply & Master Switch, identifiable by the cable connected to the pedal's front panel.

In this Flickr photo, Daft Punk appears to have a tan-colored Boss AW-2 Auto Wah pedal, identifiable by its distinctive tan knobs.

We can see GM fiddling with a white boss effects pedal with what appears to be 4 knobs, and the pedal also appears to have a single output. This narrows it down to one pedal being the Boss PQ-4 Parametric Equalizer.

The Pedal is seen sitting on the TR 808 which is in front of the Linn drum Photo taken at the Even Furthr Festival in Wisconsin 26th of may 1996

In a live photo of Daft Punk from 1995, there is a guitar pedal positioned on the left side of the Juno, identifiable by its 4 red knobs in a row, which closely resembles the Boss MZ-2 Digital Metalizer rather than other models like the Heavy Metal or Metal Zone. The distinct red color of the knobs, as seen in the image, supports the identification of this pedal. Additionally, similar tape is used to cover the model name on this pedal as seen on the 808 above the rack and the Boss GE-7 on the Linn Drum.

In a photo of Guy-Manuel de Homem-Christo's studio from circa 2002, a HAZ Mu-Tron III+ Envelope Filter is visibly highlighted with yellow arrow, confirming its use by Daft Punk.

In a photograph of Daft Punk's home studio (Crydamoure Studios from 2003, providing insight into the setup used during the "Homework" and "Discovery" eras of Daft Punk), two Electro-Harmonix EH-4600 Small Clone pedals are visible on the mixing console.

This photo shows Thomas Bangalter of Daft Punk at a live show circa 1996. What appears to be a Boss PS-3 is visible in the foreground. Of the blue 4-knob Boss pedals available at the time, the CS-2 has white knob tops and the DC jack surround was flush with the bottom of the casing, the PS-2 has white knob caps, and the VB-2 has different shaped knobs with red position markers. Some DigiTech pedals such as the DigiTech Screamin' Blues use a similar enclosure, but have a split line level with the bottom of the DC jack surround.
