Hello. So I recently got a guitar that wasn't complete. I got the parts required and I'm trying to wire it. But it doesn't sound very good. It's running active emg 85 and 81. With 1 volume and 1 tone. A telecaster style 3 way switch. I included pics and the diagram I followed to a tee. But I can't see what's wrong. It's a brand new battery

This pot looks like it was possibly overheated during soldering and might not be working as a result. There is also a lot of extra solder on the pot that could be giving you problems.
In addition, a stray fragment of wire (inside the red "circle) can cause problems if it touches the wrong part of the pot.

I can't really control the volume. It's crackles and buzzes and cuts out with volume turns. There's alot of solder because I had to undo every the last guy did and I don't have the solder removal tool. The stray wire was removed and didn't help . I tried emg solderless before this but still for some reason I had no volume control and other sound issues like cutting in and out with the volume knob at certain levels. Tried 2 solderless pots.

Than
What is not sounding good?
Examples...
No sound?
Buzzing sound?
No control of volume and/or tone?

Edit: My apologies for not welcoming you to the forum before asking all the above questions.....
WELCOME to a great forum!
Thank you!

Are these solder joints to the pot terminals touching the body of the pot?

I think it would be wise to buy a solder sucker, unsolder the pots (and possibly other parts of the circuit), test the pots (you will need a meter for this) and re-solder everything carefully and with much less solder.
I know that is not what you wanted to hear.

I can get a hold of all of that. What should the meter read when testing them?

Each of the pots with the wires removed, cleaned up and taken out of the circuit should read from about "0" to about 25,000 (or 25K) ohms (assuming the pots in the guitar are the same as in the diagram)

This might help...

You'll forgive the nosy and presumptuous question, but the solder blobs lead me to ask it: what are you using for soldering iron?

I’d personally rewire everything onto good new pots, with a nice hot iron. Rough up the pots with like 400 grit or a little coarser sandpaper where you plan to wire to them. If you have the iron, it’s just a couple pots, $40 will get you lifetime quality, $1 ea will get you minis, which you don’t want. And the switches are cheap too, if it has been similarly re-soldered.

I said earlier.
I think @mhammer is asking what kind of soldering iron you are using and if it has sufficient power to get hot enough for proper soldering.
Do you see anything on the soldering iron that says " ___ watts"?

This is excellent advice. Save yourself a lot of going in circles like I was suggesting earlier and just start with new pots and focus on good soldering technique.

By chance, does the solder you are using say "lead free"? That stuff is murder to solder with.

It doesn't seem to have the same range of degrees of turning as the volume
You could cut the wire from the volume pot to the tone pot and see if you notice any change at all. I strongly doubt that the tone pot is the entire cause of your problem(s), but it could be contributing.

Sounds like a bad / burnt / very dirty pot.

So I checked every pot and the 3 way switch. All are ok. I also removed all excess solder. But doesn't sound any better. Even after re wiring with a different diagram. I included pics of the new rewire aswell as the new diagram I used and an audio clip of what the guitar sounds like
