15mm Shaft pots are normally used for Fender style guitars or guitars with plastic pickguards that the pot goes through

18mm Shaft pots are normally used for Gibson style guitars as they often have wood that the pots must go through (or plastic pickguards if you purchase extra nut and washer to create a spacer at the back)

What is the difference between A pots and B pots?

“A” would denote an audio taper pot (most of the control happens between 7 – 10) and the “B” suffix would denote a linear taper pot (more even roll-off between 0 – 10)

A and B pots however are interchangeable and the only difference is the taper of the pot, or “how gradually it rolls off”. Most manufacturers use either audio taper (A) pots for volume + tone or would use audio taper (A) for tone, and linear taper (B) for volume. This is also determined by player preference
