Re: Les Paul + Duncan For ROCK 'n' ROLL!
Duncan + Les Paul does NOT = rock n' roll
Just kidding, its a match made in heaven (or depending on how heavy of rock, hell)
Any and all of those pups will sound darn good in a LP, just depends what taste your after.
A custom for example will have a bit of a modern metal edge to it, where a C5 will be a bit more vintage yet still very heavy, like a PAF on steriods, where a PAF will give some classic rock sounds, you get the picture
Basically every passive bucker you listed is going to sound somewhat in the same ballpark, or at least the same sport.
Its just an issue of slightly different magnets, output levels etc that will give it the character.
