Can I use these Pots?

I've read everywhere that '16mm' means the length of the Potentiometer shaft, but these just don't look right:

although after chatting with them they said they are '16mm' pots.

any ideas?

they seem pretty cheap, would it even be worth buying and trimming them down?

if not, please show me the place to go to find these at good prices, they are expensive all over eBay!

Thanks :-)

The most common places for component sourcing are places like smallbear, Tayda, pedalparts and even mouser and digikey, although the last 2 can be overwhelming if you don't know exactly what you're looking for.

If you click on the data sheet PDF in the link you provided, you can see the pot's dimensions. It shows that the sides are 16mm, not the shaft length.

Seems clear to me:

> Body diameter:    16mm
> Body depth:   8mm
> Spindle length:    38mm
> Spindle diameter:   6mm


Body is, as John says, 16mm wide.

Body-size has big effects on cost and power handling. Shaft length is a secondary concern. You can cut these. But there may be "right length" pots at the pedal specialist shops.

The more sturdy metal ones sold at the places listed above by nate77 would probably be your better bet...and you can
find them for less than the price at your link.
always think outside the box

Plastic ones are fine if you mount them well clear of the footswitch and use a low profile knob. I don't like to mix pot types (for appearances sake), so if I can't get one in metal but can in plastic, then they'll all be plastic.

^ and watch the shafts. they have plenty splined, not plenty plain. match your shaft to your knob.
don't make me draw another line.

Diameter.  For a quick reference compare to a 19mm and then to a 9mm.  Those 9mm ones from alpha can be very handy.  I rarely use the 19mm ones,  typically there is no room.
So many builds, I just can't list them anymore.
