Dude---your tech did that?
It looks like a 10 year-old did it. One thing I'd say right off--you need to get some new pots/caps in that rig. You've got great pickups; the electronics, IMHO, are robbing you blind in the tone dept. Those disk caps have GOT to go!!!
Here's a pro soldering job, done THIS weekend:
See that brown stuff on your pots? That's flux. It's applied before the solder, and eliminates oxygen/moisture in the joint. After the joint is applied, any excess should be wiped away. That stuff is corrosive over time...not good to leave in there.
My advice: either PM HolyGrail and get some good Vitamin Q caps, or go to
rsguitarworks.net - Home and buy the entire kit. At a minimum I'd get some Superpots (volume only) and Tone pots from RS.
If you need a better tech, we might be able to find you one--where do you live?
That's my 2 cents.
