For decades I used my ancient but dependable old Maestro Phaser.... Had a couple mods done to it to adjust the center frequency so I could use it for bass or guitar.
When it finally croaked I bought an MXR Phase 90 that served me well.
If you want to talk pedals, I had a BOSS flanger and an Ibanez Bi-Chorus (2 in one pedal) that I loved and only recently sold.
The old Maestro phasers were funky! In a good way too. I'm not aware of any other company that made a Maestro-sounding phaser, unless they were a direct clone. Heptode made one and the MojoHand Mister-O (see what they did with the name there?) are both pretty accurate representations of the models that only had the three switches for changing the effect parameters.
I have a Mister-O and it definitely is unlike any Phase 90 or Small Stone "classic" phase tone. Mine is mostly used with bass since it can do an almost auto-wah type thing for slapping and popping. Sounds great for that.
Lately, I've been selling off some pedals that I don't use. I'm sure that I'll regret letting some of them go (I'm looking at you, Boss DM-2 from 1981), but some of them aren't doing me any good just sitting on a shelf in my basement. I sold my DOD Phasor 201 this morning too.
