Pot speed knobs

For those who are looking to customize their China made guitars, I collected images of all the speed knobs readily available in China.

There are a lot of cool knobs out there, but you have to make sure they will fit your pots.

There are three basic types of pots, "fine spleen" which fit USA spec knobs (Gibson), "coarse spleen" which fit Asian spec knobs (Epiphone and most Chibsons) and smooth shaft which fit knobs that use a set screw like the Telecaster.

Those knobs that look like 2 stacked up are often seen on Danelectro guitars. They require a special pot as well, that is actually 2 pots in one. The bottom part spins separate from the top part, and one part is usually used for volume and the other for tone. They are called "stacked potentiometers" and are readily available.

unfortunately most of them don't have any info concerning the type of pot they will fit. I ordered a set of clear tophats, but they are too big for the installed asian pots..

hmm, the knobs fit onto the pots and the riffles grab the riffles of the pot. But the knob itself comes off too easily (it falls off when you tilt the guitar).

might this just be a manufacturing issue then?

the pot shaft is approx. 6mm
I will upgrade, but I don't think to CTS (as I don't want to increase the hole diameter).
I posted in Michaels thread, maybe he can solve this mystery :)

thanks for your help!:)

Don't forget a split shaft is adjustable (within limits of course!); if it's too large just get a pair of pliers and gently squeeze the two halves together, if it's too small then insert a flat screwdriver between the halves and gently prise them apart.
God give me patience ... but I want it NOW!!

Increasing the hole diameter is not a scary deal at all, and worth it to get top quality pots. Just roll up a piece of coarse sandpaper and work it up and down inside the hole. Check often until the pot just slides in snugly. Takes a little bit of time, but is a very safe way to do this, and zero chance you will hurt the finish on the guitar.

There is no telling what came with your Chibson. The pot itself could easily be non-standard. But yes, there could also be a defect in the knob.

Bourns and CTS are the best on the market for pots. Bourns uses Asian knobs and CTS uses USA spec knobs. But both are very high quality that will last you a lifetime.

Glad you got it fixed, but you should consider upgrading to better pots at some point, especially if the guitar came with mini pots (about the size of a dime, rather than the size of a quarter.)

Those red and black ones would look great on a black V.
