The rest of School’s pedal feast at Nashville’s Ascend: a Catlinbread SFT Ampeg-voiced overdrive, a Walrus Audio Luminary Quad Octave Generator, EarthQuaker Devices’ The Depths optical vibe, a Catlinbread Echorec, a Caroline Guitar Company Kilobyte Lo-Fi Delay, and, on the floor, a Carl Martin Octa-Switch. He’s also fond of envelope filters, but not for this gig. And Schools uses an Ernie Ball volume pedal to mute before tuning, and a Voodoo Lab Pedal Power 2 to run his rotating roster of stomps.
