Gibson's premier rock 'bridge' pickup
I cannot speak for all amps, but I can guarantee you that the Marshall DSL (dual super lead) amplifier wants this pickup on the Les Paul guitar in bridge postition. I have made it my business to review all the Gibson pickups (well most of the widely known ones, 57, 57 classic, classic+, 490, burstbucker, 500T ceramic, Burstbucker Pro, 498t, etc), and the 498T wins hand down!! Some people say pickups are pickups and they all sound the same, NOT SO!! not by a long measure.
MY LP classics came with Ceramic 496R/500T pickups that I found not terribly good. Loud, yes, musical, not so much. So I tried 498ts, Classics and the others, and never looked back.
The 498T gives sweet, smooth Rock power chords the likes of which you are not going to find on the other pickups. All of these are not exactly the same as a run by an ohmmeter/voltmeter will show, but most are in a certain range.
The best way to get to know these is to play guitars with the various pickups and see which give the tone you are looking for. I am crippled up pretty good, so it is not so easy for me to get out and about, so I have had to do this the hard way, by putting the pickups in my axes and seeing and hearing live. There's no way to go wrong with that method but it is expensive, and not the most efficient way to go.
If you are after classic rock tone, beautiful sustaining, clear, distortion and that pretty, gritty biting, snarling, Les Paul Rock sound/tone at youe bridge pickup, this is your ticket. I use gold on my goldtops and honeyburst LPs, but the nickels are attractive, too. AND bottom line, you are always going to get a sweeter tone out of ALNICO pickups compared to ceramics. The alnicos are just more musical.
If you have a Marshall amp dont be surprised if the 498t gives you what you want. If you have a dual super lead Marshall, take my word for it, this 498t is a bridge pickup your DSL amp will just love. Great pup.
