Trip Hazard 3
The Trip Hazard 3 Tremolo uses dual Silonex opto-couplers for smooth volume undulation. Photocells on both the input and shunt sections of a voltage divider create gain and loss alternatively. Thus unity gain is preserved as you adjust the depth.
Rate can be adjusted between extreme hare and tortoise speeds.
The Trip Hazard 3 can be powered by 9v battery or with a standard center pin-negative 9v DC power supply. A red LED will light up when the effect is engaged. The stomp switch is a 3PDT true bypass.
Trip Hazard utilizes a virtual ground rail splitter to achieve precise bipolar voltage. With this arrangement, the negative from the power supply is -4.5v referenced to ground. So if you are using a Trip Hazard pedal on a pedal board with a single power supply to power all your pedals, it must have isolated outputs. If your power supply has a common ground negative, the negative supply inside your Trip Hazard pedal will short to ground, and the result will be that it won't work. And then smoke might come out.
Watch your step.
