I just put a Morley JD-10 upgrade kit online. 3PDT switch and 470pf capacitor. All you do is orient the 3PDT the same way as the old X-style switch and solder each wire to the new switch (Tip: you can use tape to mark down the order of the wires). After that, you solder the 470pf capacitor to the two inner lugs to reduce RF (radio noise). The JD-10 is a great pedal. It can be made better by this low cost kit.
