From TalkBass Wiki
The idea is here to list pedals in the different categories of Fuzz, Overdrive, Distortion that have been tested and work well on bass. By that we mean no loss of low end etc. Where you're not sure if a pedal is overdrive or mild distortion, list it in both categories. Particularly important for fuzzes, list whether it has been tested on active/passive basses. They are listed in alphabetical order by manufacturer.
