Hello! How are you?
In today's video we talk about Pickups
This video is a response for Wilbur, he asked me
several months ago about how pickups work
And you should say "David, man,
Wilbur has been waiting for many months"
Don't worry about it because Wilbur Knows very well
how pickups work... This message was
to give me an advice for a video for you all
because this topic could be interesting for you
I know he is going to
publish on his channel
because he is a great guitar player but a great luthier too
And he knows about pickups much more than me
Inviting him
to publish a video about this topic
to have a more detailed information
than mine
I am going to give you an introduction more detailed than the first one
I published many months ago but enough
for him to make a more detailed video
getting deeper and more technic
because I have not that level to explain
Wilbur, here you have a challenge!
About pickups we will discuss about
3 kinds
If we do not go deep, these are all types
single coil pickups
humbucker pickups
Piezoelectric pickups
to explain single coil pickups I'm going to choose my Strat
because it is the only one I have with single coils
I talked about this one a few days ago, I let you a card
when I was telling you about the neck change
Fender stratocaster
H S S Humbucker (double) and 2 single coil pickups
I'm using it right now
to explain simple coil pickups
in this case we have two, normally strats
have three single coils
when the first strats appeared Fender did not work with double or humbuckers
till many years later
they did not introduce humbuckers (invented by Gibson)
I'm not going to go too forward
first let's talk about singles
these pickups are exactly the same model
YJM Signature
Used by him in his signature guitar
as I told you before
not only the type of pickup changes the sound of the guitar
the pickup position changes it too
both are exactly the same model but
as one of them is nearer the neck
and the other in the middle
the sound is different
I will explain simply how a pickup works
not so deep
a pickup is formed by a series of microphones or
a series of magnets with a copper coil
generates an electromagnetic field and takes care of
capturing the vibrations of the strings
but it depends where I play
for example
As you see, sound changes
as I touch the string in a different place
if the vibration is different depending in
where I play
the harmonics repeating is different and that is what makes the sound to be different
If we put the pickup in a different place
the sound captured by the mics is different
so
altoguh it is the same pickup If I play
the bridge pickup (sorry, mistaken, it is the neck pickup)
sound is different
than if I play in the middle pickup
Sorry... neck pickup
being the same model
this single coil pickups had a problem
it's tone is brilliant
and sharp
well defined
but it generates a sound
a hum
that hum is provoqued
as the electronic field
because of the way they are constructed, they
receive signals from
lights or plugs
and that provoques hum
in this case no because these are prepared to avoid that problem
but a Fender classic
with classic pickups, hum will be louder
As I said, Fender strats had at the beginning 3 simple coil pickups (today there are more configurations)
this one has a double pickup
that gives us a thicker sound
this doubles or humbuckers
As simple coils
generated hum
Gibson engineers found the solution
they used two pickups at the same circuit and
one of the magnets
change the polarity to
cancel the hum frequencies
2 pickups
and no hum
this pickups
have a thicker sound because the electronic field
has more voltage
to eliminate the hum we need to sacrifice that Fender brightness
and sharpness
you can here the thicker sound
each simple pickup model or double pickup model has its own sound
because of how they are constructed
how many coil has
there are a kind of single pickups called P90
vintage sound
single but with more coil
they has more voltage
and the sound is like a
hybrid between both types of pickups
In this guitar we have both options
single coil and humbucker
the rest I have are
two humbuckers format, but many of them have a secret
for example
I'm going to take my telacaster (telecaster only in its shape, haha)
and I tell you how pickup works in it
2 humbuckers
only thick sounds
as in the other pickups
if they ware the same model they would sound different because of their position
they are not the same model
Seymour Duncan Pearly Gates in bridge
the same as the other guitar
and a vintage Seymour Duncan SH1N-RP59
in the neck
when you put distortion on it
this pickup
sounds with many sustain and
it seems to be fuzzing not distorting
including the amp distortion
this pickup sound is really thick
and because of the position more and more
we could say this guitar is not very versatile
because we have no brilliant sounds for clean
I love it because iI love Gibson
Les Paul sound but not its weight and difficulty to play
because I'm a small guy and Les Pauls are
thick and heavy
and not comfortable
when I was searching for a Les Paul a tested this guitar and it was love at first hearing
a great substitute to a Les Paul
that's the reason I bought it
this guitar has a secret
it has push/pull, I can pull the potentiometer
and we cancel one of the pickups from the doubles
and both become
single coil pickups
and sound is brighter
If I push
sounds really different
One thing to count on
to generate the electronic field
strings have to be metallic
if we want to capture the sound
on a nylon string guitar
neither single or humbucker piclups will help
because they are not metallic
and the vibrations will not be captured
there is a solution for that
piezoelectric pickups
I forgot to tell you pickups
can use an active
electronic circuit with extra electricity
that permits
more electronic components
to change more the sound
posibility to have
an EQ in the pickup itself
piezoelectric pickups use to be active and they need that extra electricity
and they use it
to bring extra EQ effects
extra gain
I'm going to take a Spanish guitar
with piezoelectric
it is behind the bridge
in contact with the wood behind the bone
that captures the vibrations
this pickup
needs to be in touch with a part of the guitar
to capture vibrations
it translates it and sends it to our amp
these are the controls
it has a little circuit
and the extra electricity
this one is quite good
and versatile
it has a control
it says piclup
and mic because it has
"two pickups"
a mic like the one
I have on my neck
inside
and the piezoelectric pickup
you can combine both
I use to have more pickup and less mic
to have a brighter sound
it has EQ controls
too
and Contour
it plays with tone
If I move the selector a bit
to the mic
sound is
darker
now you have basic notions on how pickups work
to get more details
I show you some photos
there are pickups that are encapsulated
use to be humbuckers
but singles too
it use to be an aesthetic reason
but there is some influence in the sound
and to be noiseless
etc etc
but today's pickups are silent, including the open pickups
they are prepared to block interferences
that's why I say its an aesthetic reason
I put a foto of
P90 pickup
the single with more copper coil
it works different and
the sound is really different
and if you've notice
I have a bass with a rare pickup
let me take it
this is a split pickup
it is considered as humbucker
they are two singles
with polarity changed
and thats the reason we say it is a humbucker
but we do not loos the brightness
a single coil gives
in this case for the bass
If you see another one I did not talked about
or you want more details in a topic on the video
And I can answer of course,
I'll be pleased to answer you the best I can
OK
Be good!
