Whereas Nelson runs very few effects, Corey McCormick has a lot of tonal options on the floor. He plugs his bass into a Boss TU-3 chromatic tuner. From there, it hits a Noble Preamp/DI, a Radial Twin City ABY Amp Switcher, an Emma Electronic Discumbobulator, an Electro-Harmonix Micro POG, a Fat 314.C chorus, a Wampler Low Blow Overdrive, a Dunlop Cry Baby Mini Bass Wah, an Eventide H9, and an Electro-Harmonix Holy Grail Nano. Everything lives on a Pedaltrain Classic 2 pedalboard while a Voodoo Lab Pedal Power 2+ supplies the juice.
