Volume Pots

Volume Pots

Ok, so I changed the pickups in my mexican strat.
I put in Texas specials.
It seems really quiet. I opened it up and made sure that I didn't have
any cold solder joints etc.
It is still quiet. (Meaning that I turn my practice amp up quite a bit
just to hear it)
Could this be the Volume pot that is being used?
What is the normal value for a volume pot in a strat?

Are the tone pots and volume pots usually the same value?

Thanks

The most common is 250K, although my Dlx uses 1M. See:

for all of the gory details.

The value of the volume pot should matter so much in determining the
overall volume of the guitar (as odd as that may sound). Mainly, they
affect the tone that you get with the volume control wide open.
Different Fender models come with different values, and people often
swap them to alter the tonal response. Same with tone pots; they can
match the volume pot or not, depending on model.

If the guitar volume is a lot lower than it was before you made the
swap, there's something else going on.

Typo:

"The value of the volume pot *shouldn't* matter so much....

A rule of thumb is 250k for single coils and 500k for humbuckers.
But this aslso depends on if they are wired in series or paralel.

Pots are usually 250K or 500K. Any combination of these values is
fine. Large or smaller pot values would also work but with a different
effect on the guitars tone.

Sounds like you have a wiring problem. Try by-passing some of your
solder joints with a loose bit of wire. If the volume jumps up then
you've found a bad joint. May be a problem with the wiring of the tone
or voume pot. Try disconnecting the earth from each of these (one at a
time). If you remove the earth from the tone pot and the volume goes
up then, check the tone pot wiring. Then try the same thing with the
volume pot.

Re: Volume Pots

I was playing this guitar last night, and it seems like the tone pots
change the tone with the switch in the right position.
But, the volume pot goes most of the way around without changing the
volume very much.
The last 1/3 to 1/4 turn brings the volume up so that I can hear it.

Is it worth it to try replacing the volume pot?


I have trouble believing that I messed something up when all I did was
put the leads on the switch the same way the old pickups were
connected.
I soldered the other lead to the volume pot. (again, the same way the
old pickups were connected)


Thanks

Ok, I don't know diddle about electric guitars, but it sounds like you
may have the wrong kind of potentiometer. In addition to the value of
the pot, there's another parameter called the "taper" (in the US,
anyway). For volume control applications, you usually want an "audio
taper" or "log taper" pot.

From what you describe, you may have installed a linear taper pot.

Bypass the vol pot entirely.
Is it now at full volume?
If so, suspect pot. If not continue...

Bypass tone pot entirely.
Ask same questions.
If not continue...

Bypass switch...etc.

Bypass each component one at a time.
Find the fault, replace or repair the
component.

Work the other way around if you like.
Start with pup to amp direct. Then one
at a time add components till you find
fault. Then replace that component and
continue.

Re: Volume Pots

I've had several of my switches go out and the symptoms are the same. Pull
on all the wires, reheat the solder joints. If the switch can be opened,
clean the pcb with a pencil eraser. You can short out the pots to remove
them from the equation. You can jump the wires of the pickup to the wires of
your guitar cable to check them. Personnally, I think you've overheated the
switch.

Most guitar volume pots give a bigger volume increase between 7 and 10
so that's not usually. Sounds like you just have too little voulme
overall.

Re: Volume Pots

When I originally put the pickups in, I had a hard time getting the
old pickups off of the volume pot.
I used a LOT of heat to get the wires off the pot. I am not sure what
is inside, and how much heat it can take.

Last night I replaced the volume pot. I can hear the guitar through my
amp from 2 or so up to 10 now.

The Texas specials that I put in my MIM strat sound great now that I
can hear them! (played a little SRV last night...)


Thanks to all of you for your suggestions!
