I'm looking into new pickups.
Now I stumbled on a pickup that has a beefy sound, they say.
So how will it sound?
Does beef have a lot a mid? Low? Or has beef a nice clear high tone?
Or does beef have it all? Or should I ask the butcher?

I'm starving,  so anything sounds delicious right now..
 
 
"Beefy" generaly means "full bodied", think high gain humbucker through a Marshall stack as opposed to a single coil through a Fender twin...

Like a Les Paul through a Marshall.
Humbuckers, as Karen pointed out. 

So a beefy humbucker is, like wet water, a pleonasm........

No,  you can get thin sounding humbuckers and some that are so bass loaded they're almost unuseable (I have one like that on a cheap LP copy).  That "beefy" sound is specifically a mid to high gain humbucker through a Marshall stack that gives plenty of mid/high clarity for soloing but shakes the glass out of the windows with palm muted power chord "chugging"

An other beefy sound is a 1962 Strat neck pickup driving a 1964 Fender Twin with the Volume knob turned up to 7.
 
10 is too beefy but 7 can work... if the speakers don't come flying out of the grill to fast.
 
Here's an example on a 1963 Fender Showman;
 

 
It doesn't sound so beefy on TV but if you were in the room you'd know where the beef was.
 
A decade later musicians had gotten a lot better at squeezing the beef into the TV.
 
 
all the best,

If you buy the same pups in Tescos, they sound slightly more 'horsey'

We sound like the meat that we eat.......
 
Then maybe I need fishy pickups.....

Horsey!
