I am still contemplating a change of bridge pickup for my trans-black Shine SIL-510, the issue being that the neck P90 I fitted sounds great, but is actually putting out quite a bit more volume than the bridge, despite playing around with pickup height etc. And given I have enough guitars with a more standard kind of humbucker in the bridge, I fancy something a bit different. Looking on ebay, there are a few interesting candidates for the job. These are just my thoughts, and it should be said that although these are all aimed at the rock guitar market, I actually would be using the pickup mainly for clean tones (although no harm at all if the pickup is good for overdriven sounds, that could come in handy once in a while).
Entwistle HDN - I already have a set of these in my green Ibanez, they have very high output, the bridge pickup is 16.9K, and they have neodymium magnets. A very full-range kind of tone, kind of a "hi-fi" pickup if you like, with if anything the highs more prominent than with a PAF type humbucker. The bass end is tight, and maybe a bit subdued, but I like that, I generally have to turn down the bass control on my amp with humbuckers. With postage from ebay sellers, around £22
Entwistle Nemesis AFG - These have one coil with a rail, and one with adjustable hex-poles for the other. And different magnet types for each coil too - ceramic on one, alnico on the other. So interesting possibilities for wiring different split-coil sounds. From what I can tell, could be a bit brighter sounding than a PAF type, but that might well match nicely with the neck P90. I think they look kind of cool as well. About £29 with post from ebay sellers.
Warman G-Rail - Basically a hot-rails type pickup (ceramic magnet) paired with a strat type pickup with 6 individual alnico magnets, placed side by side. Obviously lots of wiring options there - all 3 coils have separate wires for maximum flexibility in the wiring. With 2 push-pull pots on the Shine I could wire for the following 4 settings: a) the rails pickup on it's own b) the strat pickup on it's own c) rails & strat combined in parallel d) rails and strat combined in series - this setting would have a seriously huge output lol, but might have it's uses . £25 including postage, not bad at all, and it certainly has a different look to it!
Well, there you go, I'm leaning towards the Warman at the mo but we'll see. Just in case of interest, and any other (not too pricey) suggestions welcome, cheers!
