The Pro Pot is modelled on the ICAR pots used in most late '60s Vox wahs. In my opinion it is the best replacement for a Vox or Crybaby. The "sweet spot" is a little wider and it has a nicer feel than some of the other pots on the market.
I recommend conductive plastic pots for Colorsound wahs and stock the same type used in the reissues.
I typically use 3PDT switches in my own pedals, but I also stock Carling DPDTs.
Dunlop feet, rubber stops and pot gears are all stock items.
