I was cleaning my new Les Paul and re-stringing it two days ago when I realized that, in a matter of a few weeks, I had damaged the finish on the bridge pick-up and the bridge itself.
I had had the same issue w/ my LP Junior last year, but I just hadn't noticed how quickly it happened.
I already knew that I probably had pH issues - I literally ruin pale clothes in a matter of a few hours (not that I actually wear white that often, but anyway...)
Now, ruining clothes and sheets isn't a cause for worries - but guitars?!! Oh yeah, and, eventually, there's health problems, bla bla, bla. ;)
After a bit of research, I realized that my usual diet probably really doesn't help.
In fact, among the worst offenders were coffee (I usually drink 6 or 8 every day), soda pop (2 or 3 a day), sweeteners (both in soda pop and my daily pint of Gatorade), tuna (one of the 2 animal protein I eat regularly) and beef (my occasional guilty pleasure). Oh, and beer. :(
So here I am, trying to re-balance my pH.
I decreased my daily coffee intake to 2 cups.
I cut Cola. That's the toughest one.
Gatorade - no more.
Orange juice and milk have to be monitored (tough one, I drink a approximately a pint of each every day).
Even bread has to be monitored.
Not that I can't have any of those things, but I really have to put the priority on my intake of alkaline food (mostly greens and soya). Oh and green tea. :) So I guess I'm back on the oriental diet. Rice, Bock Choy, Brocoli and Tofu, here I come.
The good news is - my Les Paul is an Epiphone - so it's not like I've damaged an (overpriced) $4000-$5000 guitar.
Plus, after only two days of that regimen, I feel strangely relaxed. Go figure....
