The True Bypass Box takes effects out of the signal chain while protecting the natural guitar signal. When they are needed they can be reinserted with the stompswitch.
All True Bypass Boxes are absolutely passive - the pedals can be used without a power supply. The pedals can be powered either with a battery or an external 9V power supply. All True Bypass Pedals now come in custom made enclosures with a beautiful, durable powdercoated finish.
The A/B Box - True Bypass Box combination has one True Bypass loop and one A/B line selector integrated into one single handy box. This allows you for example to switch all your non-true-bypass pedals with the true bypass function and to switch between your amp and a tuner with the A/B function.
