Yep!What pickups are most commonly replaced? The stock ones, of course.
Or Squiers maybe?Yep!
Usually in Epiphones and MIM Strats.
Dunno, did ya hear the one about someone pulling the N4s out of an Elite Strat and putting in Texas Specials?
Yup.
The thing is that sounding like $#!+ is generally pretty subjective and therefore can fall outside the boundaries of popularity or typically accepted “goodness” or “badness.” You or I might not make such a swap but that certainly doesn’t mean that someone else wouldn’t.
Sounding like $#!+ isn’t even the same for everyone in terms of degree. For me there’s a lot of levels between that and sounding great... like “pretty good,” “good,” “fair,” “meh,” and “boring.” It has to be really bad (to my ears) for me to say it sounds like $#!+. On the other hand someone pickier than me may think that “almost there” still sounds like $#!+. It’s still a matter of perspective, personal taste, and tolerance.
Face it, there’s just no non-subjective way to evaluate the question without access to hard data about pickups that are swapped and the reasoning behind each one. We can probably come up with some educated guesses, but the best that’s going to produce is good theories... especially within this forum where pretty much everyone likes to tinker with their guitars and experiment with different pickups. The vast majority of guitarists out there have no freaking clue how/why their instruments work and have no desire to find out.
I would think stock Fenders or Gibsons are replaced the most, since they are the most common guitars. More sold = more replaced.
Strat pickups and humbuckers for two main reasons: they are what show up on 98% of super Strats, and not many people play Teles any more.
Depends on what kind of guitars you have. Mine are either HB or P-90; I don't own, or want to own, any Fender type guitars. Other players have all Fenders, and their aftermarket PU purchases are going to be a lot of single coils. When I see bands live (mostly classic rock & blues), there's usually more Strats & Tele's than any other models (Jazz & Precision basses dominate in those genres, and for good reason).
BTW, HB's would include mini's and Firebird mini's. What about PU's with dummy coils?
I suspect a good percentage of Duncan's and other aftermarket PU sales go into mid-price import guitars, and that Epiphone is one of the bigger ones for PU upgrades. MIM Fenders and Squires are probably a sizable part of that too.
Shouldn't it be comparative to amount of sold pickups?
While humbuckers sell the most as aftermarket pickups and in guitars, it seems to me they are much less often upgraded by non-professional guitarists than single coils. I guess because SC's, especially cheaper ones, tend to take more time to get used to.
