OK, i barely post on the forums but since this issue is buggy me a lot, i need help my own guitar(which is "dead" Right now("dead" is a term only used if all the electronics are burnt or heavily damaged))

The Guitar i currently own is a used Ibanez RX-20 from 1996(which i find funny, i was born on 1998) and it was given to me by a neighbor after helping out on their home on a clean up. as soon i plugged the guitar, it started to act badly, for the neck pickup died first, then the bridge after hearing a Honorable screech. i unplugged it and i smell something was burning from the inside of it, and turned out to be the electronics died. i took out the brunt wires and broken pickups after finding the schematic for it. i posted it on the discord chat in the hats gaming section, but since i'm forced to post to it here, i will let you guys see the picture of my guitar and the schematic

IDK about what you've got burnt and what smelld to you if pickups are passive(Super58 is) there's nothing to get damage by itself(even if you got shortcuts somwhere, I suppose you've got a bad capacitor(s) check the one at volume knob, It's likely it could be bad ceap ceamic and film capacitors works not that well and youe film cap may be dameged\etc also if it's ta old...

It was plugged in one amplificator or any pedals when the electronics died ?

Or just with Rocksmith cable ?

 

(If the wires burnt the guitar may not be the source of the problem).

There is no source of power that can cause what you described. Is it possible you plugged your amp output into the guitar?

amp only, but got more info on how much damage it took, for the previous owner told he used it for over 12 years and started to sound wore out. the amp i had was too much for my guitar, so it killed it (yes was grounded but it's very old, for my family owns it).

the pickups are passive, the knobs have bad solder jobs(it was done in the 90's so it's excusable) but the jack survived(i'm still wondering why), and the switch is starting to react as the rest.

if anyone has any ideas, tell me fast

I would be worried about your amp if it fried your guitar more than anything cause amp shouldn't send power to the guitar but only receive!

Get a cheap multi meter and start checking your connections. If you have bad solder joints they will need to be fixed as they will only get worse over time due to oxidation caused by the air gap between the circuit.

did check, and they are in bad condition(i know how to solder other types of electronics) and this had those joints since 1996, from the factory. the pickups have no connection at all, leaving to amuse it's broken from the inside, i do an led test on the switch and i see it not working on the neck(i wonder why the last owner left this guitar like this), and since the joints been though hell, i maybe forced to make a new layout

I've saved a pickup once by unwinding 20th winds, scratching the end of the (very very thin) wire by pulling it very lightly between 2 pieces of 1200 grit sandpaper (to remove the insulated varnish) and re-solder everything.

ok found the culprit, the ground was disconnected on my guitar(which make things much easier, for most the components are removed(minus wires to the jack and bridge)) so now this thing is needing replacement parts for the electronics

If they cant do it then the guitar is done

Actually, it's going to be replaced, so it's dead for good. I will replace it with it's younger brother, the Ibanez GRX20. Will reuse the springs and jack for spares. Will make a new trend on upgrades I'll need soon
