Pickups wiring MOD to parallel/single coil

[Rainer Bastian]

That's interesting. I thought for a while to give that modification a try but never started because the sound I get from my Smiths never disappointed me.

Did you use the inner or outer coils ?
How was it done ? Only new soldering at the toggle poles ?

If yes, you can easily ADD the single coil option while keeping the serial option, but you will have to change the 2-way toggle to a 3-way.
