Hi everyone,

I’ve had some issues building the musikding kit of a SWAH, and I may have damaged some components.

At this point, after many changes, desoldering et resoldering… only one knob works (the upper one on the left) and does the same effect as a wah pedal from dark to trebel sound. The other 3 knobs seem not to be active. Have you got an idea of the component(s) which are guilty?

Thank you
