I have to say, I'm not super familiar with chorus. Some form of modulation is always necessary on a board, though (imo, of course). Also, I don't consider a tuner an effect because it shouldn't affect the sound at all - they are essential though, and I will refer to them as a pedal that I have.
So essentials:
distortion/od/fuzz - Ibanez PD7 / Fulltone OCD / EHX LBM
transparent compression - BBE Optostomp / Demeter Compulator
filter - EHX QTron, discobob, Maxon AF-9
phase - Psilocybe, Quasar
*I only own the PD7 and I want the rest...
I'll be able to afford them eventually.
