LET'S TALK KNOBS
In general, pots come in two standard styles, knurled, and solid shaft
Knurled (Split shaft) is a star polygon pattern that uses press on knobs
Solid Shaft is as the name sounds, a solid circular shaped shaft that uses a tightened screw to attach a knob
Knurled Shaft:Fine or coarse?
18 tooth coarse
Coarse:Tends to be the most common as it is used on most import brands likE, Bourns, CGE, etc.
24 tooth fine
Fine: Is fairly easy to figure out as CTS tends to be the only brand to use this pattern.
SOLID SHAFT: 6MM OR 1/4TH?
This comes standard on most imports including Made in Mexico guitars. It’s Just slightly smaller then the US spec style so if you are using 1/4th knobs you will need a shim to help with a perfect fit.
This standard size is what you find on most American guitars. Larger then the import style it requires that if you are changing to US from Import, that you have a 1/4th sized knob.
WHEN CHOOSING KNOBS MAKE SURE TO GET THE RIGHT SIZE
Some times sellers won't tell you, or know which one they have. So just make sure you buy from somewhere that has the size listed as 6mm or 1/4th
