According to Jimmie Vaughan:
I play the guitars I own & enjoy driving my cars. I'd never buy anything for an investment.
As such, Mr. Vaughan didn't hesitate to replace the worn necks of his guitars, even if they are worth more than the house you are currently residing in; his '58 Strat had seen at least 5 neck replacements, while his '62 sports a Schecter neck.
Regardless of how Frankenstein-ed his guitars are, they are still worth... too much.
