Looking at their Ebay store, they have one with more advanced Guyker-like tuners (for three times the price), but most of them have the same setup as mine has. A couple have more sophisticated bridges, one with a BBOT, another with individual bridge pieces. It looks quite a feasible upgrade but it all seems to work OK as it is. The extra leverage of the allen key and the fact that (like most headlesses) it's a screw thread rather than a worm gear means that it is the easiest and most accurate tuning of any bass, headed or headless, that I've used.
