How to find out what knobs fit?

Sign in to disble this ad
Just got a warmoth P bass and the bass is reliced besides the knobs, (dont really like the way they look either..) I tried taking some "worn" knobs off a tokai P bass I had laying around and they didnt fit. So is there an exact measure to use or something in which I can find out what size I need?

Do you have a ruler with inches and millimeters? It's time to get that out and use it.

Hi.

By far the most common potentiometer shaft sizes are 6mm and 1/4".

You'll need a verniers caliper to tell them apart.

Then there's smooth and splined varities of those said sizes, but they're easy to tell apart .

Edit:I'd guess that the Warmoth has CTS pots =1/4" and the Tokai has the "normal " 6mm.

Regards
Sam

yeah simple as measuring the stem of the pot and finding a knob with a hole that will suit

I agree that a caliper would be ideal, but I think that an average person with a ruler marked in mm could tell whether a shaft is exactly 6 mm or larger than 6 mm (1/4"). The difference is .35 mm or ~.016", and that's not hard to see with the eye.

But that's my experience; yours may be different.

If I'm at GC/wherever and what to confirm before buying, grab an instrument cable and stick it in the open end of the knob (seriously). If it goes in, its quarter inch. If not, its likely 6mm. Works every time.

Does Fender make any 1/4" knobs for a P bass? Or any company for that matter that will make a knob that resembles the standard P bass knob

Very clever--it's something we all have, and it gives you the answer you need in seconds. I like it!
