I've had and liked the Dunlop ZW & Slash models and the Morley Bad Horsie I, although the Morley was a bit too much on the modern side soundwise for me. I was looking at the Dunlop 95Q when I sold the Morley but found a great deal on the SW-95 Slash wah and have stuck with it for abt 18 months now. I Don't use the boost option at all but it did sound quite good when I tried the first time.
I did have the Weeping Demon too but there was something "off" in it for me. Liked the switchless design a lot.
