Local pickup only. DOOM 2 is an original fuzz circuit that turns your input signal into something resembling the sawtooth wave of a vintage synthesizer. Unlike most fuzz-style circuits, DOOM 2 responds to your playing technique and retains note dynamics. If you are even looking at this you likely have an idea of what it is. I’ve loved it I just don’t find myself using it as much as I thought I would. No duo lock on the bottom.
