All right, its been a while but I have a real quick question: Do I need a Long Shaft pot for my Epiphone Les Paul Standard? I just ordered a pair of Duncan APH-1's to replace the crappy stocks and figured I'd get 4 conductors so I could make it a Jimmy Page setup like so,

and need to know if I need long shaft and A or B type pots.

Any help is seriously appreciated .

Someone in GB&C can correct me if I'm wrong, but usually most manufacturers recommend long shaft pots for LP style guitars.

By A & B I assume you mean Audio and LInear

My guitars tend to have Audio for volume, Linear for tone. But that can be a preference thing

Yeah I heard it was a preference thing, but can someone describe the differences? I think its how they respond to you adjusting them but I'm not sure.

Also can someone recommend a brand, or would any old pot do?

It is a preference thing, try out both kinds if you can.

Bourne, CTS, Alpha, those are the big three that I think of.

I have EVH Low Friction Pots in my Rhoads, and I like them. Again, preference.

the difference is in how quickly the resistance increases/decreases as you turn the knob.
A linear pot has a uniform increase/decrease across the pot, you turn it twice the distance, you'll get twice the resistance. An audio pot (also called a logarithmic pot) increases in a logarithmic fashion, which means it will increase more slowly to begin with and much faster as you reach the maximum of the pot. Sound is logarithmic, where an increase of 10dB is equal to a doubling of volume. So by having a logarithmic volume pot you have a much more control over the lower volumes (it ends up being almost linear sounding because the pot increases at an opposite rate to the volume).

i would use linear for the tone pots and audio for the volume
i tried out using log pots for the tone knob(and vice versa) once and it was like a switch no taper just nothing from 1-9 and then 10 bam! all the way

and yes long shafts are recomended for les pauls

Not all Les Pauls need long shaft. All epiphones (minus ES) use short shaft, as do a # of Gibson LPs.

Personally I'd go with Log for both tone and volume @ 500K, it's common on HB guitars outside of some Gibson LPs.

Bourns pots are constructed w. the imperial scale in mind, so you'll have to bore out the holes to get them to fit in better. Alpha pots are metric, which will fit in perfectly with your Epiphone. CTS, doesn't make P/P pots. and uses Alpha pots on their harness that require P/Ps.

Along with all that, I'd also buy a switchcraft 3 way toggle switch (short shaft) and a switchcraft input jack. If you are redoing all the electronics, I'd replace everything.

... Also, there are many non humcancelling and dead zones on the JPLP. So, be aware.

... .... Also, Also, A .22 cap in the bridge and a .15 in the neck is a common set up verses running the .22 in the neck as well.



What you describe sounds like the opposite.
Linear pots will be almost flat from 1-7 then 8-10 they increase.
Log pots 'sound linear' in fashion, as that's how we hear.

yeah volume is finne since we hear volume logarithmically
but for tone it doesnt work so well cause of the sudden change in the curve so it works more as an off on switch than not

Long shaft pots are for going through a wood guitar body thickness like your Epi's pots do. Short shaft pots are for going through thin plastic pickguards, like Fenders. Good luck.

No, it's not bad for you at all. Don't listen to the government. Oh, sorry, wrong type of pot. Yes, you do need long-shaft pots, A is for volume, B is for tone.

The only real answer to the long/short shaft question is to take your existing ones out and measure how thick the wood is at that point.

Alternatively, if you buy short shaft and they're too short then you're stuffed. If you buy long shaft then provided the control cavity's deep enough they'll still be useable. Problem is, with push-pulls you'll not have such a margin of error.

Measure it. It's the only way to be sure.*

* Apart from nuking from orbit, of course.

All right guys thanks for the help.

I measured the shaft and sits at ~18 mm, so, long or short?
