Three things make the Horsie Wah the best wah in my opinion:
1. It is switched on by only placing the foot on it, which makes it way easier to use for short prhases, bends, etc. in solos....way easier then hitting a switch first
2. It has no pot, but works optically which makes it invulnerable....should last forever....
3. It sounds aboslutely GREAT for playing solos with high gain
It never owned a Cry Baby so I cannot comment on the differences, but I suspect the Cry Baby might sound better for clean funk rythm work....but for soloing the Bad Horsie sounds killer....
