“To A and B or not to B, in stereo - that is the question.” Enrico Shakespeare, ye-olde scribe of Berlin

There’s nothing new about ABY boxes. They’re a very commonly used accessory and a staple part of many setups out there. But if they are so common, then why is it so difficult to find one in a stereo format that’s well built, noise-free AND affordable? This is a question we kept encountering as we use many stereo devices daily here at KMA, plus we know that a lot of users are just as mesmerised by the wide sonic worlds of stereo as we are. So, we made a killer stereo ABY switcher to use here at our workshop. In the process we found it so useful, so we decided to make it available to the world too in a pedal format.

Whether you’re looking to switch or combine your stereo input signal between two separate destinations or switch or combine two separate stereo input signals into a single output, the KMA Machines STEREO ABY pedal is a dependable little helper for your tonal quest. Created with a focus on durability, reliability, simplicity and hassle-free operation, this passive ABY switcher also features True Bypass active silent relay-based soft switching to reduce mechanical noise and unwanted pops and clicks when in use. So, all you have to do is choose your path and perform!
