In case you've ever wondered what the inside of a Dunlop wah "hot potz" looks like

This one has failed - two cracks in the carbon track, and the track is really worn out.

I guess there is no way to repair a carbon track, for example with graphite lacquer applied on the old track?

These pots have such a hard life I usually just change them. I don't think any sort of repair would last very long?

Indeed, wah potentiometers have a really hard life.

New pot installed. Also needed a new switch.

Ah yes, pot price!

Quite lucky here in Japan that I can pick up a nice Montreux (branded) pot for around 2700yen versus 4400yen for Dunlop.

Most of the wahs cluttering up the second hand shops are for 2-4000 yen with scratchy pots. I now have far to many repaired wahs

I should do a deal with you to get some pots sent here
