I'm of the opinion that a man's wood is to do with as he pleases (fnarr!) However, there are countless great P basses out there but, to a far lesser extent, there's a finite number of genuine 70s fretless Precisions left in one piece.
To me it's a true vintage (and rarer) instrument so with this in mind I feel that with such basses, ownership also comes with 'custodian' responsibilities. To play it, love it and keep it safe until it eventually goes on to it's next adventure.
Just my feelings, not saying I'm right because I know I can be a dreamy sentimental old git! π
