As seen here on Ken Andrew’s pedalboard from his Fantastic Planet setup sometime in 1996-1997. Could have been used during the recording for Fantastic Planet and possibly Magnified.

Ken Andrews uses the Boss DD-3 Digital Delay, as seen on the floor during the recording of "Comfort." Alongside the DD-3, there is also a Crybaby wah, BF-2 MIJ, CS-2 Compressor, DMC Ground Control V1, and a footswitch, as evidenced by an image on Imgur.

Ken Andrews explicitly mentioned at the 15:03 timestamp that the Boss CS-2 Compression Sustainer was a key component for the “Failure Clean Guitar Sound” and was also used as a vocal effect on the track "Blank," as detailed in his YouTube video "Episode 6 - Creative Recording Techniques."

At 4:06, Ken Andrews mentions the use of a Gen 1 Mutron Phaser all over Fantastic Planet. During their performance at the Whisky in December 1996, you can even spot the phaser right next to his Mutron Octave Divider.

Used during the Fantastic Planet era as a lead boost for guitar solos, this pedal was one of the many sold in 2014-2015 during Failure's Pledgemusic campaign to raise funding for their reunion record, The Heart is a Monster.
