Resistance is futile, my friend! I tried Chromes on one of my Rickenbacker 4003s and they remain on that bass. They can sound bright or like typical flats when you want them to. Just turn the tone knob and the strings will respond. They get even better in 6 months once they mellow out. Some people change them at this point, but I don't understand why they would.
Medium gauge (50-105) Chromes are my favorite flats! I love the blue silks against my 4003's headstock.
I also have an spare light gauge (45-100) set that was cut for my 4003, but they didn't have enough tension for D Standard tuning. So they sit in a Ziploc bag with my music equipment. I don't have another bass that I could put them on either.
