The one thing I haven't gotten to yet is the suck switch. The idea of the switch, in the JS-II, which in my understanding is called a bass boost, is as follows:
The neck pickup has a resistor that supposedly balances its output level with that of the bridge pickup, since the neck position is inherently louder.
With the switch activated, this resistor is taken out of the circuit and a low-pass filter (the capacitor) is engaged to knock off some of the high frequencies. The point of taking the resistor out is that when you knock out part of the signal with the capacitor, overall signal level will drop so the resistor can be taken out, and the low frequencies will be higher, relative to the higher frequencies.
In other words, boost the neck pickup level by taking out the resistor, then shave off the top end with the capacitor. Result is bass boost.
Mine's not wired right. I haven't traced the wiring but I think someone tried to do something interesting with it but it seems to be acting like a pickup selector. I don't think I will need a bass boost switch with the bisonic, so I will be thinking about something creative to do with this switch. Maybe like unwiring it
Or see if putting the pickups out of phase with each other is interesting.
In either case the bisonic pickup is substantially louder than the bridge pickup, so I'm going to make sure that resistor is in place and if it is, I may increase its value...
