The Morley ABY was introduced in the early 1980s, but when a young engineer named Scott Flesher joined Morley a decade later, we didnt suspect his redesign would become one of the most popular utility pedals of all time. The latest version of the Gold Series comes with improved, quieter circuits and a new look. It is simple, robust and versatile. There are many different ways to use the ABY. You can route one input to two outputs or, conversely, direct two inputs to one output. This makes switching between guitars or instruments a breeze, as well as using multiple amplifiers. Plus, the device is completely passive, meaning it does not require a power source to function. Only the LEDs require electricity, which saves the life of the batteries.
