Blue shoe gai pan

Built this circuit, this is my third one and for some reason the sweep and mid control have no audible effect. Isolated the dual gain pot, reflowed all my points on the pots, push works so the haunting mids circuit is working I'm just stumped. Everything on the pedal works. Fets are biased at 4.5v. Help please!

I see. Well, I have adjusted a dust seal on the dual gang pot, but I am not sure this was enough. I am from Brazil and order a new PCB become expensive. So, I will try replacing the dual gang pot, for lucky I have ordered 2 of them (1 Alpha and 1 Tayda). I will give the Tayda one a chance, trying something else as insulation.
