Hi!

I have a BOSS HC-2 hand clapper that is broken

The problem is that it makes crackling noise when I touch the pcb.
Since the audio connecters are wired to the pcb it crackles whenever
the cord is touched.

I have almost zero experience in repairing stuff but I want to learn,
and since it's not a very expensive item, I think it makes sense to
practice on it. Taking it appart it looked to me as at least of the
capacitors had leaked? Could that generate crackling noise?

I took this pictu

What do I do?
