My main Strat has developed problems gradually over time, but it's been playing so nicely that I didn't want to tear it down to chase electrical gremlins. My one experience stripping it down, to change the wireless board and boil the strings wasn't good. It wasn't a happy guitar when I put it back together, and it took about six weeks before it finally settled in.
I've finally accrued enough other issues that it needs to be stripped down again, so I'm gritting my teeth and doing this....I have a dead #1 position on the five way switch (although the bridge pickup works in other switch positions), the three position rotary switch is sloppy-loose, and the mini-toggle that turns on and off the mid-boost has gotten sloppy feeling and the circuit's not operating properly. I think the bypass position is okay, but when the boost is inline, things get quieter and thinner sounding. I'm hoping it's just the mini-toggle rather than the Villex unit which is sealed in epoxy.
I'm also toying with switching wireless boards again. Although the channel 11 board that's in it now is still working, it's noisier and seems to have more directional issues than the original channel 3 board did. I changed the board originally because I assumed it was damaged......Thought I inserted a battery in reverse polarity and fried the board. Turned out to be a fault in the twin-9 volt battery box, which I've now bypassed. Anyway, when everything else is done, I might go back to the channel 3 board (which also lets me use the wireless receiver with the hot rodded antenna.
All in hopes that I won't have to tear the guitar apart again for many years....
This will be my first string change since I built it in 2008-2009.
