The wah pedal is of great interest , so made a lower cost one prob is that the padels go in 3k -9k range next is the pot slider mechanism that is tricky to make even if u made that the Potentiometer you cannot find locally There were thse solutions 1)home made pedal mechanism 2 )use the LDR wah as the case is not available . it is full diy and easy images :: https://s33.postimg.org/539t8v5ov/image.jpg used a watch case slice and a pastic from a adapter . padel hinge is hot glued will fit LDR wah to avoid pot( expensive) more to come cost max 300Rs , with sockets from china
