Phase 45 was created with a softer 2-stage circuitry that would be preferred for its simplicity in blending into a band's mix as opposed to Phase 90's four-stage phasing. Engineers at MXR changed the housings from the script logo to the block logo and included a return resistance towards the Phase 90 operation. It's difficult to criticize a phaser that costs just under $100 and is as user-friendly and adaptable as Phase 95. The screenplay parameters may appear unnecessary if you don't explore with phaser and amplitude position much, especially as they can sound overly processed and bland with clean notes. Overall, Phase 95 offers a lot of flexibility for the price. Additionally, given its small size, it likely has a lot better pedalboard endurance.
