Good advice from Tom above. A few additional thoughts come to mind.
For incidental / infrequent use on guitar gear, you don't need to go fancy or expensive to get the job done, but better equipment usually works better and allows you to do a better job.
You do need to acquire some basic skills, so if you are not already experienced, I would recommend watching some youtube instructional videos and practicing on some junk electronics before you apply that much heat to your guitar parts
Just rip or cut some wires off of some junk electronic gear and then solder them back in place to get some experience.
Also, when you go to your guitar, make sure the guitar is well protected just in case of an accidental slip of the hand or the soldering tool. You will ruin the finish on a guitar in an instant with an errant hot iron tip. It would ruin your day. Unless you actually have the parts removed from the instrument to work on, "mask" off all nearby guitar parts and surfaces around the area where you will be soldering with a heavy junk towel or similar - kind of like surgeons do when they are operating on someone.
Good luck - do a little preparation and you will find that it is not difficult.
