I have two headless basses, a Zon and a Keith. Both have bridges with the usual roller tuners, and I've grown accustomed to them. They are recessed, and I love that these basses are nearly always in tune (perfectly in tune!) when I pull them out of the case.
OTOH the nut end of the Dingwall headless is perfect. The no-tools clamping design, and retractable wings which allow it to be used with a hanging stand... absolute genius, and I'm green with envy that my Keith and Zon don't have those features.
I'm not going to buy a Dingwall headless, they aren't my style, but deepest respect to them for quality (I've played a few) and innovation.
