Johnny Marr’s Boss GT-100 Amp Effects Processor

Johnny started using the Boss GT-100 processor sometime around 2012, shortly after it came out. Prior to this, he had a GT-5 processor, so the GT-100 was a logical progression.

I was working on it and working on it, and […] then I programmed and copied all of the things I was doing with the analog board into the GT-100. And I’m pretty sure that it would pass the blindfold test to absolutely anybody including me, because I’ve gotten pretty good at programming those things.

Marr had the unit set up with two external pedals, with which he toggled through various sounds/presets that he had programmed.
