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!

Main Features

  • Passive Stereo ABY pedal, with active switching 
  • Sends a stereo input to two separate stereo outputs, separately or combined   
  • Sends two stereo inputs to one stereo source, separately or combined   
  • True Bypass   
  • Active silent relay-based soft switching, heavily reduces mechanical noise and pops    
  • Omnidirectional for 2 into 1 or 1 into 2 operation, plus in Stereo!   
  • Distinct LED colours, to indicate your selected signal path at a glance   
  • Durable compact enclosure for years of reliable switching   
  • Top-mounted jacks, will fit into any setup   
  • Made in Berlin, Germany    
  • Power by opt. 9 V PSU - (9 V DC, centre -, 2.1 mm, >40 mA max. current draw)    

KMA’s STEREO ABY features a fully passive design for the best signal integrity, along with our True Bypass active silent relay-based soft switching.  While that might be a hell of a wordy mouthful, what it means practically is that the audio signal itself is entirely untouched and without any colouration. Plus, you can use the device in either direction, for sending to different sets of amps or effects or for switching inputs/ instruments/devices into your chain.     

However, the actual switching is taken care of by our reliable and sturdy soft switches as a separate active circuit. By employing this switching technology, mechanical noise is greatly reduced, as is the risk of those pesky loud clicks and pops that have plagued so many boards and has haunted so many musicians, since the inception of ABY boxes.     

The bears eyes light up - how awesome is that!? Okay, besides just looking cool and fulfilling our boyhood dreams of an army of robot bears with freaking lasers as eyes, the 3 distinct LEDs actually serve a practical purpose; to quickly and easily show you what signal path you’ve selected at a glance. Red for A, Yellow for B and Blue in the centre for A&B.    

This neat accommodating Stereo device seamlessly integrates with your existing setup.  It's compact, rugged, lightweight, durable, affordable and can be powered via a standard 9V DC power supply. In addition, without tooting our own horn too much, it just looks awesome. All helping to make it feel right at home amongst the artistic landscape that is your pedalboard. What’s not to like?    

So, will you choose A, B or both? With the KMA Machines ABY Stereo, the fate of your signal is in your hands!

My Dog's All-Time Favorite Toy
Color: Pink, Style: Grunt Sound
The first one of these I ever got her was at Petco on sale for $1 - best $1 ever! The reviews are right, though. The toy doesn't last forever and it's not good for aggressive chewers. In my opinion, however, that doesn't make it a bad toy. Here's why: Aggressive chewers comments: Getting my sister's French Bulldog a stuffed toy (that's shredded in 5 minutes), compared to my Pitbull who does not tear up any toys, but is a stronger chewer when it comes to bones. My pup does not tear this up at all, but my sister's dog would. My point is: Don't get your dog a soft toy if your dog ruins soft toys. Regarding the not long-lasting comments: the honking noise mechanism inside eventually pops inside the hole, rendering it honkless. Ours lasted about 6 months. It's pretty much impossible to fix unless you want to trouble yourself to fix it for 1 good honk each fix. I would, but I do also have a job to get to. My dog does still carry it around in it's noiseless state, but she doesn't play with it with the same enthusiasm. How did I resolve this? I bought her 5 😂 She's only on her second, but I decided to stock it because they were on sale for $5.10 - I don't think I will get rid of any of them. I will just let her play with them on rotation until they fall apart. Besides all that, my dog just simply loves this toy. I have never seen her so happy & playful with a toy. I can't promise this for your dog, as I can only tell you about mine. We even have a "Sheepy" song. [I have not been paid or given free Sheeps - my Sweet Pea just really loves her Sheepy]

Loud! Just Like She Likes It
Color: Hedgehog, Style: Big Squeak Hedgehog
My Great Dane loves this noisy toy. She prefers squeaky toys with loud, unusual squeakers. (I need to invest in earplugs.) She's not an agressuve chewer or rough player so this should last a long time. Like most squeaky toys she has, the squeaker wears out before the physical toy does and once the noise is gone she won't play with it any more. If others have a similar issue...check with your local animal shelter. Some (not all) will disinfect used toys for the dogs in their care.

Fun while it lasts…
Color: Pink, Style: Grunt Sound
Fun while it lasts. Doesn’t last very long. This is our third one and last maybe a few weeks. The part that makes noise comes detached inside which causes to toy to no longer make noise, but also can be dangerous if it comes out.
