EDIT: P/J kit sold!
I have 2 kits for sale, I made to experiment with the new CTS switch pots and they work very nicely. Both have the Series/Parallel switch on the tone pot, new and tested.
Kit 1 To fit a standard Jazz 4 hole bell plate. £50 posted 1st class signed for UK. The S/P switch terminals are very close to the jack socket but with accurate fitting - no problem. I can supply fitted to a new Jazz bell plate in chrome or black for £10 extra.
