No way you can avoid the drill - to be honest, I chickened and asked a local luthier to do the dirty work.
The pan pot doesn't have a full off position - you go from all bridge pickup, adding more and more neck pickup, then a center click with both equal, and on to less and less bridge pickup until you get to all neck pickup. With the standard pickup selector switch, you have neck only, or both pickups, or bridge only, or no sound (which is not a true standby, because the battery will still drain).
The 3-way Q switch was indeed plug & play for me but I sent the whole lot (preamp, pots, switches and jack) over to Santa Rosa. The standard 2-way gives you 0 or 8 dB boost at the cut-off frequency (at 0 dB, there's still the natural bump of a LPF). I had mine wired for 0, 3 and 6 dB - I found the 8 dB a little harsh, and those 3 dB increments are just strong enough to make a difference.
If you spend more time here, you will find that vintage British cars and Alembics go together well - you'll fit right in.
