So I recently bought a used yamaha rbx375 and the only problem with it is that some of the knobs are loose and one actually came off while I was at school. I found it, but I don't see a screw or anything, so how do you put these on and tighten them? It's this kind:

Thanks in advance, mates!

if the pots are split post then you just slightly widen the gap with a flat tool, a flat head screwdriver works well. Just wiggle it in the gap and put the knob on, try to pull it off and repeat if it is still to loose. just be very careful as this could break the post if you force it too much.

I own the same bass, got it new and it's brilliant

Anyway, on mine there's a small hole in each knob with a thing for an Alan key/Hex wrench. It's really small.

So I just stick something in there and twist?

That something being the correct allen wrench or whatever as specified.

an alan key yes. I've never had one actually come off but that's how I tightened one that was loose.

Just used a nail. It wouldn't work for all of em so some are still loose but I got the one that fell off back on so that's all that really matters. Thanks guys!
