Is there a solid fuse-like item that I can use in place of a fuse, to bypass it?

Sorry, but I disagree from extensive listening and testing experience

your trivial sensory experience has been negated by ’expert‘ opinion.

consider yourself chastised by a higher authority…;)

There are several counties where it would be illegal were a manufacturer to supply equipment without a certificated fuse installed.

Of course once they have done so its down to the purchaser as all bets are then off.

Do not do this. 

Better question is why would you do this?

Get a good fire extinguisher a fiberglass rod and thick rubber gloves. Like the tech that works on my Tesla.

As usual, you are missing the point....

If the corrosion is bad enough to the point where it introduces excessive resistance to the circuit, everything will be affected of course. The device may not even power up properly, let alone just the sound aspect of it.
