So, I have an early Korean MTD Kingston I won when I was playing Ebay roulette many, many years ago. It has been roundly abused through the years with multiple pickup/preamp combos going in there. I should have kept the Audere preamp with the Low-Z switch . It was intense. Anyway, I LOVE the neck on it. It is (apparently) asymmetric. It is quite thin and just feels fabulous in my hand. I have other basses and sometimes wonder if I could have the necks re-carved into something similar. I know that if I change the mass of the wood then the way the instrument responds will change. It is entirely possible that I should not be trying to fix things which are already working. But I cannot help but wonder. Is this a thing people have done?
