Would the Duncan '59 bridge pup be described as warm?

There are certainly warmer pickups than the 59 but I think the 59 will deliver what you are looking for - certainly wamer and more vintage than the 498T. It's quite "PAF-ish" sounding, with good warmth and a lovely sparkle in the highs. I much prefer the 59 to the JB - which is warmer, fatter and louder.

 

"warm" is one of those buzzwords that means different things to different people. the 59 is a good, balanced (lows, mids and highs) medium output pickup. you hear plenty of the character of the guitar through it, so it might be chunky in a les paul and twangy in a` strat.

 

the '59 is not a hot pickup, more medium output. it's a nice vintage sound, but i would not describe it as "warm." frankly, it's a bit bright for my taste at times in my hamer (i favor warmer tones). it obviously depends on the guitar. it sounds good in my hamer, but i've definitely heard warmer vintage-style bridge humbucker tones from other pickups. examples: duncan antiquity in a klein with a solid rosewood neck, and the lollar in the collings I-35. in those, it's a combination of the guitar itself and the pickup contributing to the warmer tone, as they're a bit different than a les paul. the duncan seth lover is supposed to be a bit warmer sounding than the '59, and is a vintage style humbucker, so you may want to check that out. (although keep in mind that it is not wax potted, if that matters to you.)

 

I don't hear mine as warm at all in the bridge, to the contrary, it's bright (though not piercing as some bridge HBs can be).

 

I have one in the neck of a Heavy Relic tele below

I would have described it as warm and smooth
huge contrast to the bright and bitey nocaster bridge

I have the setup below tuned to G for Stones stuff
it does "not" do a great Honky Tonk Woman

the neck alone actually sounds like a warm smooth Les Paul
it's quite good with distortion

 

I would agree with the '59 being a bit bright, great for jangly classic rock. It is pretty well balanced otherwise, and it offers nice clarity as well.

I don't care for the JB because I think it's bright and a bit piercing, the '59 isn't like that. It's great for the neck for sure, but I would look for something a little darker in the bridge.
