Sizing and Backing Options

Picking The Right Size:

Potentiometer Shaft Size:
Each knob comes with two shaft options. (This is important)
1: 6mm “push on” style knob for average potentiometers. (with 18 spline shaft)
2: 6.35mm Set screw style for the larger solid shaft potentiometers.
(Potentiometer sizing and installation photo and video examples here)

Not Sure?

In many case the 6.35 style is the way to go because it can fit most shafts and stay on because of the set screw.
There is no “D” style… only Zule.
At this time, there is no “D” style shaft option, though depending on the side of the knob’s pointer, and the side of the set screw, the 6.35 can work on “D” style shafts, (Sometimes)
(“D” Potentiometer photo and video examples here)

Most Knobs are offered in 3 sizes. (Small, Medium, and Large) – this is different than selecting the shaft size, and purely effects the size of the knob.
* Large is usually the size of a standard guitar knob (Sometimes slightly larger because these knobs are larger than life… even if that is only 2 or 3 millimeters larger… (Ha)
* medium is the smaller size you might see on some guitars and effects pedals
* Small is for effects pedals and other small electronics.

Art:
Once you know the size knob you need, and the size potentiometer it needs to fit… there are some art options.
Small and Medium knobs all have a plain backing. (No options yet – so thats easy – no choice to make)
Large Backs have artistic options. (See below)
– Note these are not visible when installed unless the knob is cast in transparent or clear material. If the knob is opaque/solid – the art on the back wont matter, other than it’s cool and you know it’s there… but yeah, no one else will ever see it.
