KMA Machines - Active ABY
Active consistent connectivityABY boxes are not something that will set the world on fire. We know that. But what a good ABY box can do, is start a flame that’ll fully ignite your creativity, and our Active ABY pedal is a REALLY GOOD one. Expertly built, noise-free, gorgeous looks AND affordable – it just ticks all the boxes.
As an additional offering to our Passive ABY box that has graced thousands of rigs the world over, the Active ABY is ideal for those who like to use the Y splitting or combining functions – at least with some signals that don’t always play nicely together, due to often differing impedances between connected devices. With KMA’s high quality active buffer, the pedal can also help with level mismatches or signal loss due to long cable runs.
Whether you’re looking to switch or combine your Mono input signal using two separate outputs, switch or combine two separate input signals into one output, the Active ABY pedal is a dependable little helper for your tonal quest – the fate of your signal is in your hands!
