This may be common knowledge for folks here, but thought I'd share anyway.
Many of us have had this issue where a split shaft volume pot gets pinched in, either by trying to screw in a solid shaft pot or otherwise. If you squeeze too hard, you can even shear off part of the shaft. Knobs then don't stay on, or don't rotate correctly on the pot.
On my MIM Jazz Bass, I had lent it to a friend and noticed the bridge volume pot knob was rotating freely and fell off in my hand when I barely touched it, and sure enough, the shaft was bent inwards.
I remembered a video on stewmac.com, and took one of my worn out Dunlop Tortex .73mm (the yellow ones), cut it down with scissors, and then cut a second one. I carefully opened up the split shaft prongs with a flat-bladed screwdriver enough to slip both pieces of the pick in, and then pressed down the volume knob on the repaired shaft. Problem solved, and total cost was $0.
This can also help if you want to install solid shaft knobs with set screws on split shaft pots. Not usually a problem in audio gear, but on guitars and amps it can be.
