Hill’s bass goes from his Shure wireless system into an amp splitter, into Marshall JMP-1s and Valvestate Pro 120/120s, into a DI. He uses two only two effects: An Electro-Harmonix Micro POG Polyphonic Octave and a Micro Thumpinator to filter every note below B flat. Hill’s rig uses 3 channels: clean DI, an octave down DI, and a dirty amp channel.
