Ctrl-X is the first and only onboard mixer that will combine traditional passive magnetics with new-generation active electric guitar piezo bridge pickups, such as the powerful L.R. Baggs X-Bridge or T-Bridge. With the Ctrl-X, you can mix an active piezo electric guitar bridge with your magnetic pickups without active circuitry ruining the sound of your magnetics. The Ctrl-X combined with the X-Bridge will allow you to upgrade your Strat to the performance of state-of-the-art hybrid guitars at a fraction of the cost.
