An "Utility" Tool Designed for Modern Rigs
The KMA Machines AB/Y fits within the philosophy of "utility" pedals: no frills, just a reliable routing tool that solves very practical problems on a pedalboard. Designed and manufactured in Berlin, it emphasizes robustness and ergonomics, while offering a real advantage over traditional ABYs: a relay soft-switching system designed to reduce mechanical noise and unwanted clicks during path changes.
Who Is the KMA Machines AB/Y For, and In What Scenarios Does It Make a Difference?
This pedal is aimed at any musician (beginner or pro) who wants to manage an audio signal cleanly without complicating things. Live, it quickly becomes indispensable for instantly switching from one amp to another, activating two amps in parallel, or selecting two instruments without unplugging. In the studio, it serves as a quick switcher to compare effects chains, reroute a signal to two destinations, or centralize a minimalist setup.
It is also well suited for "old-school" pedalboards (fuzz, vintage circuits, sensitive chains): the concept of a passive audio path and true bypass aims to preserve the natural behavior of your guitar and the response of your pedals without adding unnecessary coloration. Blues, rock, pop, indie, metal, ambient: this is not a "style" pedal, it's a "rig" pedal.

Questions frequently asked
Can the KMA Audio Machines AB/Y send a signal to two amplifiers?
The omnidirectional system allows 1-to-2 routing to feed two destinations. Channels A and B can be activated together to combine both paths.
Can it select two guitars to one amplifier?
In 2-to-1 wiring, this pedal allows selecting two inputs to one output. This operation is especially suitable for switching between two instruments without unplugging.
What power supply is needed for this ABY pedal?
A 9 V DC power supply with center negative and a 2.1 mm connector is required. The maximum current consumption is 40 mA. Battery operation is not supported.
Is switching between A and B silent?
Channel selection is based on soft-switching relay switching, designed to reduce unwanted clicks. Multicolor LEDs immediately indicate the active routing.
Does the pedal alter the guitar sound?
The passive audio path and true bypass aim to preserve the signal without added compression, EQ, or saturation.
