There's a brief youtube demo of Chromes on an SB-2 which makes me think they would be a very safe choice. The MFDness seems to take precedence over the flatsness, making a very strong firm tone. I guess DTFs are a bit of a risk, but I can feel the gold and tort goading me.
I'll have to go take a listen. Pretty sure I have an unopened set of Chromes kicking around in the parts bin… Most of my basses are wearing various flats. Part of me wants to keep rounds on it for variety, part of me wants flats because that's what I generally play these days. But I'll leave the rounds on for now, I guess. Or maybe I'll pull a set of something off another bass just to see how it sounds with flats. Ugh, so many options.
