Oh your one of those contrary types Gabriela Hoffman, huh. I see you had something to say about everything I posted.....
Prove it, how could I to someone who can't hear the difference? Although my winder says that Tele neck pups don't sound different with or without the cover, I disagree with him too but at least he has a body of work to support his opinion.
Hardly, but I've been building electric guitars and replacing pickups for 23 years. I'd say that I have a pretty good basis for comparison. Our shop manager has been doing this stuff for 30 years, and he agrees with me. One of the best guitarists I know is a good friend, and has better ears than any single individual I have ever met. He agrees with me. In fact, I don't know one person who has ears I trust (and I know a LOT of guys with great ears) who can come up with any consistent difference between with or without covers. Which means whatever they are hearing isn't about the covers.
Like I said, the only valid comparison would involve being able to unsolder and remove covers in about 1-2 minutes - including the unstringing and restringing of the guitar - so that you can actually remember what you heard, and how you were playing. Which is impossible. You simply can't remember fine detail in sound any longer than that.
This is one of those audiofool - err, audiophile things. The best example was the two guys who were fighting over which $1,000 plus speaker cable was better, so they had a third friend run a blind test. Both the audiofools agreed - the $0.50 wire coat hangers were the best speaker cables!
Or the guys who send their expensive vintage Martin's to be "voiced" by some guy somewhere, who proceeds to remove required structural parts of the guitar, put on new strings, and then send it back. The main difference the owner hears is the new strings, but six months down the line he can't figure out why his guitar is falling apart. But he spent $1000+ on it, so it MUST sound better. (Of course, he could have had the same sound improvement by spending $10 on new strings, and his guitar wouldn't be falling apart!)
You EXPECT to hear a difference, so you hear a difference. Bone bridge pins? Complete snake oil (though they do look kind of cool), but try convincing half the population of the Unofficial Martin Guitar Forum of that! Even if pickup covers do make a difference, could you honestly tell
which was which if you didn't already know? Not a chance. There are too many other variables, from a players pick attack, the freshness of the strings, the ambient humidity, etc. for you to narrow it down to one thing. Which, as far as I'm concerned, means it makes no difference.
