KMA Machines Launches ABY and STEREO ABY Pedals

KMA Machines Launches ABY and STEREO ABY Pedals

Created with a focus on durability, reliability, simplicity, and hassle-free operation, these passive ABY pedals feature KMA’s TrueBypass active silent relay-based soft-switching.


ABY boxes are very commonly available accessories from a multitude of manufacturers, so why did KMA decide to make their own? What’s on the market today is either generally low-cost, with clunky and loud switches (that tend not to last) or they are highly specified and therefore quite a lot more expensive than many people need.

In addition, it is difficult to find an inexpensive and simple ABY device in a stereo format. With the popularity of stereo pedals, KMA made a great little STEREO ABY Device to use in their Berlin workshop and in the process found it extremely useful. So, the brand decided to make it available as a pedal to the world.

Created with a focus on durability, reliability, simplicity, and hassle-free operation, these passive ABY pedals also feature KMA’s TrueBypass active silent relay-based soft-switching, to reduce mechanical noise and those nasty unwanted pops and clicks when in use. The 3 distinct LEDs also quickly and easily show exactly which signal path has been selected at a glance.

After 26 years, the seminal noisy rockers return to the studio to create Rack, a master class of pummeling, machine-like grooves, raving vocals, and knotty, dissonant, and incisive guitar mayhem.

The last time the Jesus Lizard released an album, the world was different. The year was 1998: Most people counted themselves lucky to have a cell phone, Seinfeld finished its final season, Total Request Live was just hitting MTV, and among the year’s No. 1 albums were Dave Matthews Band’s Before These Crowded Streets, Beastie Boys’ Hello Nasty, The Miseducation of Lauryn Hill, Korn’s Follow the Leader, and the Armageddonsoundtrack. These were the early days of mp3 culture—Napster didn’t come along until 1999—so if you wanted to hear those albums, you’d have to go to the store and buy a copy.
