or not... i used a Phase 90 because it has a smaller phase range, helping to keep the low and high end present, and only just phasing a decent section of the midrange. however, some might prefer other phasers with larger phase ranges. play as many as you can, and buy the one you like the most. get familiar with it's sound and what it does to your tone, and when you're playing a song that you just think needs the phaser, use it!
Phase 90 was a little too subtle for my likes, but a great starter for phasers! :]


, Here is a video for those who haven't heard the song in a while -
