The Dual True Bypass Box takes two effects chains out of the signal chain while protecting the natural guitar signal. When they are needed they can be reinserted with the stompswitch.
The construction is absolutely passive - the pedal can be used without a power supply. The pedal can be powered either with a battery or an external 9V power supply.
The Dual True Bypass Box has two loops that can be switched independently. It is possible to bypass both loops, have either one on, or both on at the same time.
Two LED indicators show at all times which loops are engaged.
Mint condition including box.
