The Funk Box 95 is an auto wah that is quite sensitive to picking dynamics. Made in Japan in mid to end 70s
 
It gives an effect similar to a wah-wah pedal, the difference being that the Funk Box 95 is electronically triggered by the player's attack on the strings as opposed to the mechanical and foot action on the wah-wah.
 
It has the same quality as its predecessor, the Funk Box 90, but the difference is all frequency type; you can attack on any string (from 1st to 6th) at the same level.
 
Rare to find pedal!!
