What is the draw to these tuners? I recall the more deluxe versions of some American made Jazz basses had these some years ago and have been looking at necks to find that some of the more expensive ones have these tuners installed. Is a lighter weight desirable on the headstock or just contributed to a lighter overall bass. ALL of the older/vintage J and P basses obviously had the originals, what could have been wrong with that? Or is it just bling/gimmick or personal preference? Sorry for the new bee scooby question, looked around but couldn't find anything without sifting through 10,000 threads.
