Re: Duncans that sounds good with poplar
I have an 88' Charvel Model 5 and i am thinking about pickup replacement. the body is poplar, rosewood board, maple neck. i am into classic, thrash metal and blues. the amp i am using is Randall Diavlo. currently i really dig the tone of JB in my Jackson Dinky. i am looking into something passive, with strong mids and a bit of agression.. also, if anyone own this guitar, the tremolo is not sitting in the body, it's actualy raised up so there is enough space for floating it back. so i wonder if i should get humbucker or trembucker for the bridge?
Almost certainly a TremBucker, given you have a vibrato bridge.
As far as pickup choices, there's lots of choices that could work, depending on what flavor you want.
For gonzo metal insanity, I always recommend the PATB-2 Parallel Axis Distortion bridge. I generally can't stand ceramic, but it lacks the ugly ceramic presence/treble bite that bothers me in every other pickup [Ceramic TB-5 Custom is probably a distant 2nd for best ceramic as far as I'm concerned]. PATB-2 sounds like the best parts of a Distortion, JB and Invader in one pickup. Only caveat is it might have too thick lower mids for your taste. But for screaming harmonics, reduced string pull, crazy sustain, and just sheer metal madness it's hard to beat if you like a hot compressed pickup. More and broader mids than the Dist/JB/Invader.
If you want something more flexible, a PATB-1b Original Parallel Axis might suit. It's somewhere in between a Custom 5 and a JB in tone, but very dynamic, more high end than the JB but sweeter. Harmonics still wail out, but are broader, rather than the focused scream of the JB. Low string pull, enhanced sustain and very responsive to touch and pick dynamics. Can squish almost like an A2 if you roll off the tone and soften your pick attack.
If you are comfortable with swapping magnets, a TB-5 Custom with an A8 magnet might suit. Has a strangely modern vintage feel, an open roar. Surface54 [Surface-X on soundcloud/youtube] used to have some great demos of it doing thrash metal. It basically rolls off the treble & upper mids from the ceramic, emphasizing the midrange a bit, very slightly softens the deep bass, but keeps most of the punch & output.
Some people argue the Alternative 8 does the same thing, but it's louder and more compressed, and loses some of the qualities I love about the Custom 8. If you aren't put off by a hair of ceramic bite, the TB-5 Custom might do it for you stock, though.
P-Rails [particularly as a set with a matching Triple Shot] is another fun oddball. 4 great sounds in one pickup: Series is a tone zone-ish hot fat humbucker, parallel gets compared to a light bubbly PAF, P-90 and a single coily rail mode. P-90s are highly underrecognized for metal [probably due to fear of noise problems. Noise gates aren't that uncommon now, though...] Not a jack of all trades, master of none, it's great at all of it's modes. Many people "only" like 3 of them, but there's considerable disagreement about which 3 are best.
Or if you want a stock, familiar-looking trembucker, you could look at a Perpetual Burn [underwound JBish, designed for Jason Becker] or Pegasus.
Or just go with another TB-4 JB, and if it is too bright or not punchy enough, look at magnet swapping with an A8 magnet.
