I have the Deluxe Moon Phaser and use it all the time. It's great! Totally changed my "sound." I have been waiting for the Empress chorus to come out and will probably buy one this week. I have been waiting for the sound clips to appear and they did today. I realize this may sound stupid, but what is the real difference between the two pedals? That is, I realize they are both modulation effects. If I have one, will I "need" the other? I realize I wouldn't have them both running simultaneously, but is there going to be a difference it the tone that each one will give? I must admit that I am "new" to phasers. I have had a TC Electronics Chorus for years and years and take it for granted--never think too much about it. Any tips or suggestions would be appreciated...but as I mentioned, I'll probably end up getting the Empress this week since I like the Moon Phaser so much! Thanks.
