Thanks for the reminder - hopefully it will be Howard to the rescue - yet again !!

What's the exact problem here? Are they missing or just slipping and not holding tune? I can help with the latter.
Cheers
Jules

Thanks Jules, they work OK - it's just that two have been replaced by 'one piece' units and are not black - mmmmm - so it looks like I need the knurled knobs 'and' the thread assemblies

All the best

Ive a jack that i love and never seems to goes out of tune.

I'm interested in what causes the slipping issue?

Ch guitars? If you go to a guitar tech, they have loads of knobs/switches etc.

they don't slip at all - just not black, or original - damn OCD !!

The threaded portion of the tuner knob is steel and the slider/string retainer is aluminium, so a lot softer. The thread in the slider can just strip, especially if you don't keep them well lubricated. I've fixed this on a couple of Jack Basses by drilling and tapping out the slider to take an M4 Helicoil, a steel threaded insert. There is just enough meat on the slider to do this, and it only takes about 5 minutes if you have the Helicoil kit.
