Knobs for unusual shaft

[James Nada]

I've recently required an old Marlin Slammer bass which had some unusually shaped, small pot shafts.  I need a couple of knobs for it, can anyone point me in the right direction for some suitable new knobs?

Bearing in mind the ancient pots and the chances that they could well be naff, I'd replace them.

yeah, I'd put nice new pots on there and then choose knobs at my leisure

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.

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.

Disappointed here.

A woman walks into a bar and asks for a double entendre, so the barman gives her one.

Ha -  I had one of those as my first bass. £99 from the Littlewoods catalogue in 1987

I have in the past seen knobs with a "D" shaped hole underneath for those type of pots but I would think that regular round shaft knobs would fit as long as you tighten the grub screw into the rounded bit and not the flat bit otherwise it would push the knob in at an angle

Be careful with the bridge - the chrome peeled off on mine.

Thanks for all the replies.  I've actually managed to use two "normal" knobs with grub screws - just wrapped a fair bit of plumbers tape around them.

The neck is currently in s g-clamp in an attempt to fix the bow.  Oh, and I'm going to ignore the huge cracks in the body and call it road wear!

What I didn't mention is that this is actually the bass I learned on, and was my Christmas present in 1989!  It's been at a mates house for years in less than perfect conditions.

It's still fared a lot better than mine. I defretted my one with a huge flat file before chipping the paint off and eventually binning it in 1991 and getting a Riverhead Jupiter
