Rewiring a hollow body

[pingu]

hi there ,

can anyone recommend a good
supplier of wire , Pots etc etc
in the UK

I have an intermittent fault with
my Af120 I cannot for the life of me
track down

so I’m gonna bit the bullet and
make up a new loom for her ….

many thanks

update I believe I’ve found the problem ….

when i squeeze the neck pu volume pot I get the loud buzz back

good I’ve found the source of the fault

so I now just need a 500k pot
should I get audio or Log or Linear ?

what is the best make to get ?

(I don’t want the ones Gibson use
with all the change happening between 10 and 6 on the dial)

I want the one Gibson don’t use

Given a choice, I use CTS pots, for the volume control you'l want an AUDIO taper, not linear. BTW audio and log are the same thing.

It could also just be a loose solder joint... the pot may actually be fine.

Working on hollwbodies sucks. Good luck.

thanks for the advice
(it doesn’t appear to be a loose
solder joint , unfortunately)

From reading around I think I’m
leaning towards a Linear Pot

I want to get an even volume
change throughout the pots travel (as per my Ibanez guitars)

not like a Gibson 335 I had
where most of the volume drop happened between 10 and 6 on the dial
that was too sudden a change for me

Is it still an Audio taper I need
for that ?

No, what you want is a linear taper.

The only difference I've noticed between audio and linear taper pots is where the jump happens. Both will give a small arc where a big difference in volume happens. I prefer audio taper, but it's not really that big of a difference to my ears.

The whole idea of the audio pot sweep is making it sound linear... because the human ear doesn't hear things the way mathematics might suggest it should. Audio taper is supposed to sound smoother than linear taper for VOLUME pots. That's it's design purpose. There are a few people who prefer linear for volumes, but builders use audio and the vast majority of players use audio.

Use whatever you like. But just because the linear pot sweep on paper is actually linear, that's not the way the human ear hears it.

This is from Lindy Fralin, famous pickup winder:


LINEAR VS. AUDIO TAPER?

We get asked about Linear and Audio Taper pots a lot. Despite choosing which resistance of Pot to go with, there are two types of Pot “Tapers.” Taper refers to how the sweep acts and sounds. Is it smooth and gradual? Or, quick and abrupt?
LINEAR POTS:

Linear pots are, well, linear. Imagine a straight line on a graph: electronically, your wiper and taper is just like that – a straight line. You would think that this is the end-all, be-all of pots, right? Well, the human ear doesn’t hear that way (there’s a thing called the Weber–Fechner law).
What happens? 90% of your perceived signal change is found in the first 25% of the turn. That means you turn your Pot a little bit, and the bulk of the change happens right there. Not very useful for specific applications.
AUDIO TAPER POTS:

Audio Taper pots are different from Linear pots as they are logarithmic. Imagine that straight line, only curved in the middle. The result is an exponential increase or decrease in resistance as you turn the Pot.
What happens? You experience a smoother change when you turn the Pot. This means that you can perceive a 50% loss in volume at the “5” mark!
We prefer Audio Taper Pots for Volume and Tone, but you can always experiment!

update

I believe I’ve found the source of me
intermittant buzzing fault

I think it was a bad solder joint
to the back of the Volume pot

I have made it good now ….
cost zero

very happy
thanks for all the advice folks
