On this page I will eventually discuss straight filter effects (mainly graphic EQs), exotic filter effects (Moogerfooger MuRF comes to mind), and the mundane filters behind every "TONE" control most distortion pedals have, the sculpting EQ controls such as on the Boss Metal Zone, and the filters you don't know about that clean up your analog delays and clean up your power. (Some of this info may be available already in other corners of the site...)

The phaser effect is technically a filter effect. The type of filter is called an "all pass filter" in that it does not reduce the amplitude of the incoming signal, but it does change the phase of the signal. The "all pass filter" will be posted here at some point.
