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.
*Trip Hazard pedals utilize a rail splitter for precise bipolar supply voltages. This means that if an external power supply is used to power the pedal, its negative rail will not be ground but -4.5v. If using a pedal board-type power supply for multiple pedals, it must have isolated grounds on its outputs.
