> "to use the Q-filter with Bill's 5 way for Tele: do you just connect it to the tone control as normally??"

You've got several options:

1) If you're the kind of player who just leaves their regular tone control at 10, you can simply wire the Q-Filter like a capacitor, and your tone control will be a Q-tone control. At 10 the Q-tone and regular tone are the same.

If you like to roll back your tone control, you have two main options:

2) You can employ a push/pull tone pot to switch between regular tone and Q-tone.

3) You can have both a master tone and a master Q-tone, either on two separate pots, or employing a stacked pot.

It all depends how much tone control you want.
