Kens' Comments: All of these pots have the same length shaft which is the proper length for 99% of guitar amps.
There are (2) standard bushing diameters, 1/4" & 3/8". The bushing is the threaded part that fits into the hole in the chassis.
Most chassis holes are made with a 3/8" hole for pots so both the 1/4" and the 3/8" types will work.
All of the knobs that we carry will fit on all of our pots.
