Are ABY boxes giving you a headache? Our ABY Pro Selector is just what the doctor ordered! Based off the original Morley ABY Switcher our Pro version is equipped with new features that will help solve issues commonly faced when using switching devices for multiple amps. New features include a higher enclosure for easy access, a custom built Morley 1:1 isolation transformer, silent switching, a reverse polarity switch and a ground lift switch.

PLEASE NOTE! DO NOT use on powered speaker lines. You WILL damage your amp, speakers or both!
