I'm confused. got my new bass, Yamaha 1024 BB... I put some flats on it (105-50 chromes), but I couldn't get the action anywhere comfortably playable without buzz. Took it to my trusted dealer, and he said the action I wanted was pretty much impossible. (I had it set up the way I'd like it to be, with the buzz occuring). He is setting the bass up at the moment, so I can see how it feels when set up by a pro (he has 40 years of experience, so I trust his judgement). Now I am confused. With the rounds on it, it felt perfect, a lot easier to play, and the action at least felt a lot lower. Is this due to the high tension of those chromes? Do I need less tension and a smaller gauge of flats to get the same nice feel? I am not too experienced in setup and flats.. on my squier, I could get a playable action even with the heavy labellas. Would the lightest set of chromes feel better, or do I need a low tension-flat like TI ?
