Allparts EP 0220-008 Brass Pot Sleeves

I need to find an usage for this.... Perhaps like bits of hardware for other applications. All Parts sells this for pots with cut shaft before using a screwable knob to avoid your shaft to be damaged with the screw. Until this point all is perfectly met. But now, the problem to notice. The only knob I found that will fit when you use this sleeve in combination with a pot, is the pricy Fender one. I do not see the point to buy less pricy pots + sleeves + Fender Poti-knobs and not to buy also the solid shaft pots. Final price will be more or less the same. Otherwise you can keep your pluggable knobs on the cut shaft pots and you save some money. Thomann HB brand has beautiful pluggable knobs for little money that fit the good Goldo Alpha Pots (made in Japan) and you do not need all this hassle.
