Chris Martin

Visible on Martin's pedalboard in Coldplay: Live at Glastonbury 2005 starting at 7:13. The SD-1 is shown up close at 7:34.

The same pedalboard, once again to the right of Martin's piano, is visible in archive footage from the Twisted Logic Tour in Coldplay: A Head Full of Dreams at 1:18:32. An identical backup pedalboard can be seen in the background on an amp, next to Martin’s Vox MKIV Teardrop.

This blog post from Coldplay's official site tells about Chris Martin playing with Noel Gallagher. Noel plays a loop through the ZVex LO-FI Loop Junky, which Chris Martin thinks is "the most amazing thing he’s ever heard." Noel later gives the pedal to Chris.

At about 2:50 Chris Martin can be seen adjusting the TC Electronic Ditto Looper.

Visible in archive footage from the Twisted Logic Tour in Coldplay: A Head Full of Dreams at 1:18:32. The Micro Amp is on a pedalboard to the right of Martin's piano. An identical backup pedalboard can be seen in the background on an amp, next to Martin’s Vox MKIV Teardrop.

The same pedalboard, once again to the right of Martin's piano, is visible in Coldplay: Live at Glastonbury 2005 starting at 7:14. The Micro Amp is technically shown up close at 7:34, but it is barely visible due to being obstructed by the adjacent Boss SD-1.

Chris Martin listed a Boss TU-2 amongst his equipment in Coldplay's self published E-Zine in 2003.

In these images we get a very rudimentary look at Chris’s Viva La Vida Tour pedalboard. Taken from around 58:09 in Coldplay’s 2008 BBC performance (viewable here: https://youtu.be/yi-AvQDRlsw), a few pedals are recognizable. Though extremely blurry, we can make out the glossy green frame and two-switch configuration of the classic Powerscreamer, a longtime favorite of bandmate Jonny Buckland. This pedal likely made only two appearances in this performance, in tracks ‘God Put a Smile Upon Your Face’ and ‘Chinese Sleep Chant’, alongside Chris’s Telecaster Deluxe.
