Solid Shaft Split Shaft
Barrel knobs for solid shaft pots – dead easy to identify a solid shaft pot, just like the photo really – rather than having a “2 part” post on your pot, you’ll have a solid cylinder with a diameter for 6.35mm (or ¼”), and your old knob will definitely have been secured by a small grub screw half way up the side.

Solid shafts normally turn up on guitars produced in the USA and Mexico, primarily the Fender® Telecaster® and P Bass® (but not the Stratocaster® and Jazz Bass®!) - but as always, never say never when it comes to these “rules” and it’s always worth checking on your guitar regardless.
Flat topped knobs for Split Shaft pots – now this is where the fun begins! As always when dealing with knobs and pots – worth finding out what shaft you’ve actually got on your guitar – with a Split shaft, as the name suggests, you’ll have a post, divided into 2 separate sections, looks a little like a tuning fork, with a toothed edge running around the edge

Most of the time – if you’re dealing with a guitar produced in the USA (or Mexico) – and you’ve got Barrel knobs as standard, you won’t have split shaft pots on the guitar.

However, guitars from the far east, 99% of the time, always come with split shaft pots, and plenty of those turn up with barrel knobs as part of the package – Ibanez®, ESP®, Epiphone®, all fall into this category.
