I've got this Aria Pro which was a gift from a friend that I'd been messing with for a few years and didn't even know it had a coil tap. I recently decided to put a new humbucker in the bridge and put some decent hardware on it. I'm still waiting for the bridge to show up for a central ground or whatever, but I slid on the old bridge that is missing a claw to solder to just to see if I could hear it through an amp. It made all sorts of buzzing and other noises, but it actually worked (my first wiring/soldering venture). My question is that could the central ground be responsible for all the noises when turning knobs, or would that be just old crappy potentiometers? Or bad wiring/soldering? The guitar was doing this before I wired it, and it wasn't grounded then either. I'm just looking for an opinion that might speed things up for me while I'm waiting for parts to arrive. Also I was wondering if the wiring for the push-pull tap in the 1 humbucker 1 vol. 1 tone w/coil split schematic was right-side up, and if I could use it on either a 500K volume or 250K tone pot. Any help is greatly appreciated.

Just replace everything in there? Bizump

welcome to the forum!!

id say the crackling pots need to be replaced if they cant be cleaned. a spray contact cleaner should work if its dirty but some pots are too far gone.
with a humbucker id use a 500k pot

I figured as much. I just kinda hoped my initial little handy work would do the trick.
