I don’t understand why some people are puzzled by the idea that someone would rather have a lighter bass than a heavier one. Why is it an issue for those who don’t have that preference? You have so much choice in what type of instrument you play; brand, model, colour, pickup type and number, pick guard - yes or no and what kind, 4 or 5 strings or more, active or passive, matching head stock etc, etc.
All these choices and more are yours to make. Why is light or heavy, just one of those choices available to any bass buyer, such a puzzle to you?
To me it doesn’t even require justification. It’s just a choice in bass characteristics.[/QUOT
