It’s actually impossible to read the comments on that page, the scrolling banner at the top changes height depending on contents and the comments just shift up and down all the time. Website and guitar designers are the same team maybe 🤷♂️
(Or maybe it’s my phone)
If you also meant explain what it does (rather than why it’s there):
- the lever is a detuner, you can tune to whatever note lower than E and use it at the flick of the lever.
- the round knobs are fine tuners
- there are bolts to lock the saddles in place
- you can also swap the saddles around to change the string spacing
I thought they all that the Steinberger bridge. Mine has. Love how chunky it is, and the tuning is super stable.
i don’t use the detuner much. I am surprised to hear it can snap, it looks very solid.
I’ve got it on my watch list, I am keeping an eye out for a travel bass. I am not entirely convinced by the addition of the leg rest - any real need for it?
They all seem to be more pedal or amp style knobs - I guess these pots tend to be used for this kind of devices rather than guitars.
For instance:

But to answer the OP’s question, I believe these are called Flat Shaft pots or D Shaft pots. Searching on eBay for “D shaft guitar knob” returns a few hits.
The Schecter Ultracure is fitted with Ernie Ball Hellcat VI Custom Strings (90-75-56-44-34-24) as standard. Maybe your authentic sound is with light gauges
I currently use Rotosound Swing bass 66 strings.
I'd like a set of D'Addario NYXL because I don't like tuning, I am rubbish at it, I spend ages getting that needle to stay in the middle. I could do with strings that have 131%greater tuning stability
That. And if the shop do nothing contact Fender UK directly, you never know. I have dealt with Fender UK after the shop that sold me a bass went under and they sent me spares no problem (but it was still under warranty).
