Are amp knobs interchangeable?

Are the shaft sizes on amp pots all a standard size like the shafts on guitar pots? In other words, are amp knobs interchangeable?

For the most part, yeah, unless they're those cheapo D-shaped shafts that the knobs have a D-shaped hole for.

As Gilmour said with the addition of saying that they and guitar pots are generally 6mm shaft size.

Do you only have American guitars, or only imports?

 

[Modern Saint]

Kind of yeah, kind of no. If the knob has screw to tighten, it will work on most pot shafts. Usually the tough ones are the press fit types, those you just gotta try.

Just like guitars, there is a lot of variety in amp pots.

Shaft diameter
Imperial vs Metric
Round vs D
Smooth vs Knurled
Solid vs Split-Shaft
Metal vs Nylon

Many knobs will fit several pots, but they aren't all universal.
