or just make the bridge from zinc...

 
The sacrificial anode is simply an antioxidant in that it is preferentially oxidized or corroded ... in other words ... it goes away.  So using a component of your instrument that has to maintain its mechanical integrity is probably not a good idea.
 
There are other issues that would make the implementation a sacrificial anode difficult.  They are most effective when the two metals are in physical contact with an electrolytic solution (fancy talk for salt water).  If there is salty sweat on the strings but the anode remains dry, its effectiveness is probably reduced (I'm guessing).

My SG's original bridge became corroded due to sweat on it where my hand would rest as I played.  I had to eventually replace it and that one also corroded. The combination of salt and acid in the sweat. I tried to wipe it off every night but some always remained and over time it took a toll. When gigging for a living, I changed the string on a weekly basis regardless. But they got wiped down every night and sometimes in between the sets too if it was an especially hot stage.
 
Acid levels in the body.  Yep, we should be on the Alkaline side of the scale for optimal health.  With 7 being neutral, the ideal location is 7.3 to 7.6 or so.  Diet is a major factor in those numbers as is what you drink. Water being best, natural juices next and soda and artificial stuff dead last. 
 
Testing should be saliva after you wake up and wash the mouth out with clean water, let it come back to a natural state by waiting 10 minutes or so and then test it.
 
There is a belief among many folks into natural health practices, that acidic bodies are generally prone to sickness and disease and alkaline bodies are generally healthy and that diseases can not get a start in an alkaline environment. Adherents to this belief also believe some forms of cancer can be stopped dead in their tracks and reversed in a few weeks by keeping the PH levels above 8 for a time period of several days. It's based on how other living organisms react in adverse PH environments. Kinda makes sense. I had a garden some time back where I had gotten into the lazy bad habit of dumping the ash from my wood stove into the garden all winter long. I tilled it up and planted veggies in the spring. Nothing seemed to be growing like it should....plants were weak and yellow and sickly. I checked the soil PH and found out the ashes had sent the PH way off the scale. I added the proper ingredients to bring the PH back to the normal range for the plants and in a few days there was a major improvement in the veggies and the garden started to flourish. Most seed packs give you a specific PH range for that plant. Hydrangeas which have normally blue flower heads in most soils will produce pink flowers if you add a bit of lime to the soil to change the PH. 
 
If PH matters to plants, certainly, it matters to humans and could in fact influence whether we are healthy or sickly in the long run.

Wow... that is incredible. On the UP side, you should really be getting to be a better and better player all the time. It's the 10,000 hour rule. Gladwell wrote a really interesting book on the subject and gave many examples, including The BEATLES who, became SO head and shoulders good because of more than their talent and place in time BUT because of playing the Cavern (or another club) in Hamburg where they had to play 8 hours a day all week and did it for a year or more, IIRC. http://en.wikipedia.org/wiki/Outliers_(book). I liked the book. I am amazed at what you have done to that guitar in 4 months, Gibson should hire you to age their CS guitars!! Roight??

Did you test while you're playing?  Maybe it's higher during that time...

An essential test is first thing in the morning, when you've been at least 6 hours without urinating. Then take 2 or 3 more tests throughout the day and take an average.

Not good enough. What you need is a years worth of results tabulated in a series of spreadsheets and colorful pie charts.
