I don't like the sound of MM-type pickups with the coils in parallel, whilst in series they can be overly mids-heavy. I trust Shine to make a great quality bass in terms of fit and finish. I'm looking at the bass as being 95% brilliant, whereas the pickup might be the weak link in the chain, purely because fat humbuckers tend not to crop up in the middle position of 32'' scale length instruments.
It is a big pickup of a known, fairly standardised size that is in a good position on the bass. Too many hollow or semi-hollow basses use idiosyncratic pickups in weird locations, either right up at the heel of the neck or right up at the bridge. I've never been that impressed with the Epi Jack Casady basses I've tried, and again that pickup is pretty much a bespoke item. The Aria TAB66 bass has weird minibuckers right up against the bridge and neck, with a gaping void in between. The Epi Casady bass has that transformer system, which I'm not dead against, but it is more idiosyncratic technology on a fairly budget bass. The Warwick Star bass is out of my immediate price range, the Fender Coronado is sodding heavy and the couple I've played have felt totally dead. Everything Italia make is ugly, in my opinion. The Guild Starfire II reissue is more my thing, but again it is out of my price range.
