Last night my trio got a request to due Purple Rain. It is a tune we do and we always get a great response from it but it is a song with lots of open space for colorization. I normally play it clean with no effects but last night I just decided to kick on the Phase 90 and had it set to about 4 o'clock and it was perfect. It just gave that lovely thick swoosh that really made the effect sound like it was on everything, not just the bass. I find that of all of my effects the phase 90 is one of the more effective and really adding to the texture of the entirety of the song.
