You can literally short the input to the amp and be fine. In fact, cheap cables do this all the time. There would have to be a major issue with the amps isolation between the preamp and power amp to have an issue. This is possible, but a rusty pickup is not really the issue. You're simply ill-informed. It happens to the best of us.
Have you ever studied Samuel Goldwasser's PhotoFacts?
I have. I've actually studied it so many times that I know the typical failure mode of electronic components in almost any situation.
Amplifiers are powered by transistors (or tubes back in the day, not much difference). When they happen to be stressed to the point of failure, they practically always fail as a short circuit.
Short circuits aren't fun, that's why they invented the Variac to properly test suspicious devices.
Edit: I hate to repeat myself, but would you plug in a rusted toaster? Do you not value your life, or would you rather test the components and clean things up first?
If you don't understand the difference between a toaster and the front end of an amplifier, then you've outed yourself.
Also, no. Nobody tests their toaster when they plug it in.
No, everyone tests their toasters when they plug them in. Only the dead don't report results, so the results are biased towards the living.
Please tell me WTF is your problem with maintaining a guitar?
Lol. If someone plugged in a shorted toaster, it would trip a breaker at worst. But survivorship bias is an awesome mental gymnastic. 8/10.
And nobody is arguing against maintaining a guitar. Just that you are being dumb. And maybe are a troll.
You mean you have no respect for electrical safety? None whatsoever? So you'd be okay if someone threw a live toaster in your bathtub?... 🤔
Bruh, get real, you have no respect for electrical safety. Go screw an outlet if you're so confident..
Gee, the bathtub isn't the same as plugging it into the wall. Is it?
No, it's not. And you know it's not. But you probably don't know why it's not.
Or you are a troll.
Or perhaps there are already videos about such risks?

I've built multiple amplifiers from scratch, both tube and transistor based. But go off.
Good for you, awesome! Have you stress tested your circuits with corrosion to see what may or may not fail first?
http://repairfaq.org/
Nobody asked you what you could build from fresh scratch, I'm asking you what you'd do with electronics that have 15+ years of salt water vapor damage...?
Yes, I have experience with old electronics as well, and guitars, repair work, the whole lot. And I have an bs in EE.
But none of that matters because what is really happening here is that you are wrong, and instead of learning and moving on with a better understanding, you are tripling down and pulling the wool over your own eyes.
And you and all of your friends are dismissing safety. Fuck all that, I respect safety and always have. You've got mains going into the amp, the cable going into the guitar, and metal wires on the fingers. Oh, don't forget about the metal whammy bar...
Although the risk of electrocution is minimal, it still exists. My folks had a rule to not fuck around with sketchy equipment. What the fuck is your deal with cleaning and maintaining a goddamn guitar?
Lol. Nobody is saying to not maintain a guitar, wtf. What a wild stretch. You must be defensive.
They are just saying that you are wrong that a rusty/shorted pickup is some serious safety risk. Because it is not, and you are acting self-righteous, ill-informed, and paranoid.
Yeah, and the guitar only has 5 of 6 strings, and some nitwit asked how it sounds...
Get real, lemme ask you how a 6 cylinder engine would sound with a dead cylinder. Lemme ask you how a motorcycle would drive with a broken spoke or two...
Nothing that relies on timing is gonna sound right without proper maintenance. I mean goddamn, at least WD-40 the existing strings and tune them first, how TF anyone gonna judge the sound of a corroded guitar without a basic checkup and cleanup?
What the fuck are you talking about. Did you forget your point?
No, I did not forget my point. I'm referring back to the start of my points, which all basically add up to inspect, clean, and repair the thing before hooking it up to any device connected to mains electricity.
I've been electrocuted over 20 times in my life. There's no obligation that one has to perish for it to actually qualify as electrocution.
This is a consequence I've had to accidentally suffer multiple times to know what the fuck I'm talking about.
Meanwhile, shared from another user in the thread: https://youtube.com/watch?v=xS_5K5YEYv8
"or severely injure"
Yes, please don't try to tell me how many times I've been electrocuted by over 20,000 volts.
No, I have enough diagnosed brain damage already, thank you.
So you wonder why I'd rather play things safe now? Like I dunno, clean everything first before plugging it up?..
Outside is corroded from years of humidity means inside is corroded from years of humidity as well. How much? Who the hell knows? Fuckit, let's just plug it up and cross our fingers...
Or maybe, just maybe, use a little lick of sense and at least open it up and look inside first. Fuck, at least look first, not like it's rocket science to use a Phillips screwdriver to open the cover...
When I see corrosion, I don't trust where electricity goes. This is just common fucking sense to anyone that understands squat about electricity and values their life.
Hell, even if the outside of the thing is perhaps only 3% corroded, the inside could be 33% corroded...
Nobody knows unless they at least inspect it to start with. I mean hell, I've dealt with flooded cars before, you know how many of those are outright deceiving and totally ruined internally and go to scrap?
It's not hard to check inside of a guitar though. Is there something wrong with at least checking and cleaning it up first, inside and out?
That isn’t a brag. I’ve joined the 240 club once.
The guitar also has closed back pickups. So say OP takes them out, how will they see the coils? You have no clue what you are talking about.
Have you joined the 20K volt club? I have, multiple times, I used to repair CRT and projection set televisions. Ever been popped by a flyback transformer?...
They measure the voltage by the inches of the spark. You want your heart jump started? 240 club is almost a joke, except that I hear 240 makes your muscles clinch up.. ☹️
You don't see the coils to find issues nitwit, you use a multimeter and/or an oscilloscope. Shit can and definitely does fail internally where your eyes can't see.
That's the whole reason they make advanced testing equipment. pLEaSE sToP BOthErINg mE!
No, you did. And now you are trying to downplay the original argument.
That's good. It means you can learn and move on. If you aren't just a troll.
Can I buy you and boba a beer?
No. But a whiskey with ice and water would be lovely!
