When using two of the TW Pickups in the same instrument it is not recommended that BT or BQ Systems be used. Each pickup requires a push/pull pot for switching from single coil to dual coil so the balance control included with the system can’t be installed.
If you want to use the balance control, consider switching single/dual coil outputs with a DPDT toggle switch(s) instead.
