Since I'm putting new electronics in my guitar soon, I have a few questions about pots and such.

Pot differences

What is the difference between 250K, 500K and 1M pots for volume and tone controls? Will it make any difference if I don't use a pot for tone at all? I heard from somebody that having at least one pot for tone is good, because even though you might use the knob only fully open it improves your tone.

Push-pull pot
I'd like a coil tap for my humbucker in the bridge. I heard you have to use a push-pull pot for that. I have seen some descriptions and a few pictures of these things, but I'm not shure how you use them. Is it 2 pots in 1 combined? Do you have to sacrifice a tone or volume knob for it?

On/Off switch
Is it possible to replace a tone pot for an On/Off tumble switch that kills the volume with one motion instead of having to fidle with the volume knob or noise gate?

These are my questions. Thanks for reading it and any help you might give me

A 250k pot with giver a slightly warmer tone, and is usually used with single coil pickups. The 250K pot bleeds off some of the high frequencies to ground. 500k pots are usually used with Humbuckers. 1Meg-ohm pot will attenuate even less than a 500K pot, so if you want to hear your guitar "wide open" you may want to try one.

A push/pull pot is what it says, when its in normal posisiton you control the tone of the pickup as a humbucker, when its pull up you control the tone of the coil you have tapped. http://www.stewmac.com/catalog/images_1lg/3738_1lg.jpg

And yes you can use a SPDT Switch as a killswitch.

This applies to both volume and tone pots, or just the tone pots?

Their bo such thing as a "tone" pot or a "volume" pot, what determines if the pot is a tone pot or volume is the wiring.

I knew that, but what I was asking is, would you use different ratings for the volume&tone knob, or the same?

same

k, tnx

I just bought 3 500K pots. According to the shop guy, there is a small difference between tone & volume pots. Tone pots are linear taper, and volume ones are audio taper. Small difference, same price though.

theres a capacitor wired to the tone i think.

yes there is.

It is correct that tone pots are usually linearly tapered, while volume pots are usually not. It's not neccessary though, just quite nice.
And yes, there is a capacitor wired between one of the "edge" connectors on a tone pot and ground. Otherwise it would just function like a volume pot.
