Not counting the stuff that's always on, and therefore not regarded by me as an 'effect', here are the effects I use, in order of most frequent use in our songs:
Distortion (Aguilar AGRO)
Fuzz (Wren & Cuff Tall Font Russian)
Octave Up and Down (EHX Micro POG)
Wah (Modified Morley Power Wah Boost)
Flanger (DOD FX72 Bass Stereo Flanger)
Filter (Digitech Bass Synth Wah)
Octave Down (Boss OC-2)
