In the words of MXR:

The Phase 95 combines the Phase 45 and Phase 90 circuits in a mini housing with about half the footprint of a standard MXR pedal. The 45/90 switch toggles between the Phase 45
modes subtle two-stage phasing and the Phase 90 modes more pronounced
four-stage phasing, while the Script switch toggles between two phasing
styles.

The Phase 95 may be small, but its full of rich phase tones, and itll
take a beating on the road.
