1975 MXR Phase 45 Script Logo Original

Dating from 1976, this is an original MXR script logo Phase 45. The Phase 90 is perhaps better known, which is a 2-stage phaser. The 45 is a single stage phaser, so the sweep isn't quite as wide, so the resulting sound from this one is a bit more subtle. Good if you don't want to intense aeroplane effect, but want that signature phaser sound.

The backplate is not the original, but is still an MXR one, but white instead. I'm going to assume it's from a Micro Amp boost of a similar era.
