| Hi,does any of you guys know what Capacitor should be used with 250k pots,and does it really matter what type you use?does things have to be compatible. ??? |

Michael, I was in electronic repair for several years, don't claim to be an expert but allot of additional info would be needed to comment on your question.

| On some guitars, a .02 is used and others, a .047. In tone circuits on guitars, lower voltage ratings of 25 t0 100 volts. Use a non-polarized ceramic or film type capacitor. Check out Fender's website for wiring diagrams. |

What pickup or pickups are you using, what guitar, and most importantly tell us what sound you are after? Why do you think you need a 250k pot in the first place?

Generally, a 250K pot is used with a single-coil pickup. If it's a tone pot, doesn't need to be logarithmic. I've seen caps as high as 1mfd, to get more of a "wah" effect. But Fender likes those .047s.
Humbuckers use around 500K pots, and a .022 cap, but a 350K pot will do just fine. Still, you need log pots for volume, and linear pots for tone.
And Jerry is right. If you need a .022 cap, don't try to use an electrolytic cap. I like film, but it really doesn't matter. Seymour Duncan, Dimarzio, and a lot of other folks have lots and lots of diagrams.
I would add, don't be fooled by brands. There are no "Bumblebee" caps out there. Get something cheap.
It ain't rocket science! And you don't owe anybody here an "explanation," or a reason why you're doing whatever you're doing. |

Early Emmons used 100k pots. My early Sho Buds have 500k.

0.047 100 volt chocolate drops.

I checked another old Sho-Bud. It has 1 meg pots -- perhaps because long shafts were needed to go through the end of the guitar so volume pedal style pots were used.

To be perfectly clear... are you trying to create a tone control, or are you bypassing your guitar's volume control? And what kind of pickup is this for? Is this even inside a guitar, or a pedal... or in an airplane?

| Thank all you guys, for all your info on the above subject,what it i purchased a gibson body,no electrics at all just a wooden body,? over here in the UK dont have much choice on parts so a Telecaster bridge pick was fitted with 250k pots and a Cap .47 i think,the only thing that i find that there is not to much bass on the tone control so i wonderd if i should use a different capacitor. |

A cap that is .47 is a VERY large value for a high-cut (tone) cap. Most are somewhere between .002 and .047, and the larger the number, the more high frequency attenuation you will get. Keep in mind that tone caps do not add bass, they take away treble, and this gives the impression of having more bass. The voltage ratings are meaningless for tone caps, since the voltages encountered are always less than one volt. The size and shape of a cap is determined by the type, the voltage, and the capacitance. But in general, what "works" is determined by what you're looking for, which may be different for most every player.
If the cap you have is .47 and you do not have much bass, you either:
a.) have it wired wrong
b.) have a bad pickup
or
c.) you're using a really crappy amp

If you really are using a .47uF cap it will short most of your signal to earth... It's ten times too much, go with .047.
