Yes.
Install a switch.
but what's the point? The switchless allows you to do things a normal wah can't. Play a riff, then wah in quick and stop... how to do that with switching wahs especially if its a fast riff? That said, haha, not many riffs out there demand that.
And anyway, if you don't play with transistor based dirt pedals... or you play with buffered dirt pedals... then, just leave it be.
