Got this off the ‘Bay a couple of months ago to experiment with a wah, but I’m ore of an Envelope Filter player, so it’s been sat languishing in a cupboard after a couple of uses.
Treadle works identically to the Dunlop, in that the wah automatically disengages when you take your foot off.
Adjustable Q and Range controls on the side as well as a boost circuit. The wah mechanism is optical, so no worries about the pot wearing out either.
