hi Matteo, here are my favorites in analog domain:

  1. BBD i.e. analog delay:

    EHX DMM - vintage, warm repeats, classic
    Boss DM-300 - same as above - probably my all time favorite
    Dynacord SRS-56 - dual mono bbd, dark but thick

  2. Reverb: Music Thing Spring Reverb - i use medium Accutronic, and large old Hammond tank

  3. Flanger: MXR126 Flanger/Doubler - Reticon chip. wide bandwidth, feedback polarity, cv

  4. Phase Shifter:

    Small Stone - vintage rev2 & 3 - classic sound for deep cosmic levitations
    Phase 100 script logo - classic opto phaser, think gary numan cars, genesis etc

  5. Chorus/Ensemble/wow+flutter:

    Synthoma Elkorus - original bbds from eminent stringers, triple bbd, two lfo, stereo
    Ibanez BC-9 - double bbd with indiv rate/depth
    Shallow Water - tried one, its on my shopping list
