You should definitely check out the Night Witch. The Fuzz side is really great too, although probably a little light on bass. I asked him to make me a standalone phaser, but it didn't happen.I remember seeing a few Night Witch mentions but I didn't look hard. I'll check it out. As for the 99, I'm not sure what I'd do with TWO Phase 90s in this case... Are the LFOs independent? I'm always trying to get a deeper cut, not more slices, if you know what I mean, which is why I like the old Small Stone. A family member used to have a Mu-Tron Bi-Phase that I always used to fiddle with in my youth, and that to me is the ultimate of what I'm talking about. Too bad they're so sought-after now.
The phase 99 is independant or synced, depending on where you have the button set. It can get really cool playing off itself with a low and high speed. It's a killer pedal, although my Script 90 reissue is a great one if you want a nice simple phaser.
I'll have time tomorrow so I can do a simple demo of the night witch and the 99 for you. Let me know what settings you are particularly interested in for the 99.
