How It Works

Using our T2-Switch, you can

  1. Turn the Bridge pickup On,
  2. Turn the Neck pickup On,
  3. Turn the Bridge AND Neck pickups On in Parallel connection and in Normal Phase
    (the above three pickup tones are what you get with the stock 3-way blade switch.)

    (the below three pickup tones are ones that you cannot get with your stock instrument.)

  4. Turn the Bridge AND Neck pickups On in Parallel connection and in Reverse Phase
    (gives you a glass-shattering country twang tone you can't get with the stock instrument.)

  5. So with Switch SW5 in the Down position, you get the four pickup tones described above. You can turn on the Bridge pickup by itself, the Neck pickup alone, both the Bridge and Neck pickup together (in normal phase), as well as the Bridge and Neck pickup together (in reverse phase).

    When you put Switch SW5 in the Up position, you get the following two additional pickup tones with both pickups connected in Series. This gives you a warmer and more humbucking Jazz tone, that you just cannot get with your stock instrument.

  6. When you turn on both the Bridge AND Neck pickups On in Series and in Normal Phase
    (gives you a Humbucker-like Jazz tone you can't get with the stock instrument.)

  7. With both the Bridge AND neck pickups On in Series connection and in Reverse Phase
    (gives you an intense country twang tone you can't get with the stock instrument.)

You get six pickup tones with this upgrade.   < Less
