Is the guitar already HSS? And you're replacing just an existing bridge humbucker?
If it works as is at the moment, you've already got pots/etc that will do a job, if not the job.
In that case, in your situation, I'd probably leave the wiring/pots as is at first and see what happens. If you do it that way, the wiring/soldering is not too difficult. Go slowly and methodically (only undo the wires that need undoing to take the old pickup out, make a note of where they went, etc).
If you're new to soldering, maybe practice a bit first, and get ready for burnt fingers! I learnt to solder inside guitars and never damaged anything. I tell a lie - make sure you protect the finish with old towels or something! You learn that pretty quickly - hot solder and soldering irons go through guitar finishes very easily, burnt fingers heal quite quickly, guitar finishes don't :lol:
I reckon you could do it, and you'll feel better for it. And, in the long run, learning to do this sort of thing yourself is loads cheaper. But, if you do decide to take it to someone, there's no shame in that either :D (the best would be if you know someone who knows about this stuff, and they're willing to do it while you watch).
Welcome to the forum :D
