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 thickReverb: Music Thing Spring Reverb - i use medium Accutronic, and large old Hammond tank
Flanger: MXR126 Flanger/Doubler - Reticon chip. wide bandwidth, feedback polarity, cv
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 etcChorus/Ensemble/wow+flutter:
Synthoma Elkorus - original bbds from eminent stringers, triple bbd, two lfo, stereo
Ibanez BC-9 - double bbd with indiv rate/depth
