I'm on a bit of a phaser quest at the moment. It started with my Yamaha MagicStomp which has some great phasers in it, but it's not too reliable and I'm looking for something standalone.
I had a Small Stone nano but it was too muddy and had a volume drop. I got a Boss PH-3 which sounds good on Rise, Fall and 10 stage. The 4 and 12 stage modes are too muddy and the 8 stage loses bass.
This week I got a Pigtronix EP-2 which is cool but despite its features, it still seems limited (haven't tried it in a band setting yet).
Now my attention turns to the Empress Phaser. It seems to have all the features I could dream of (except a centre freq control) but I don't know how it sounds on bass.
The things I like are: dynamic and LFO; adjustable dynamic attack and release; tap tempo; lots of modes, waveforms and ext control options; and perhaps most importantly - clean blend and adjustable gain. And the overall attention to detail. There is soooo much packed into this box!
The shortcomings might be the fixed frequency centre and the phasing stages limited to 2, 3 or 4. I guess these could hamstring it's usefulness on bass.
I've seen a few people on here speculating about this thing, but has anyone actually used it?
BTW, here's an overly detailed review of it on guitar
