I don't know why Ibanez persist with the chinese licensed Barts, they're terrible things IMO. So dark and lacking any real excitement in the mid or highs, it's no wonder Bartolini gets a bad name when these licensed jobbies are in so many budget instruments (US Barts are a completely different kettle of fish). I'd much rather they put Nordies or any other decent pickup in and dropped the preamp to save costs etc.
Frustratingly, I love the roasted maple neck on some of these, but every one with a neck like that on is equipped with those Barts. And they're an awkward size to replace too (6 string bass pickup shape, so only bar magnet 6 models will fit).
