Heritage Audio Synth Buddy Passive 10-to-1 Stereo Source Selector Switch

Heritage Audio Synth Buddy: A Passive Stereo Source Selector

The Heritage Audio Synth Buddy is a passive 10-to-1 stereo source selector, routing up to ten stereo line-level instruments into a single output with no power required. It solves the everyday headache of unplugging and re-patching synths every time a new idea strikes. One turn of the switch swaps the active source instantly and silently. Because the design is fully passive, it adds no coloration and needs no power supply.

Ten Stereo Inputs, One Output

Up to ten stereo sources, or twenty mono sources, can stay connected to a single stereo destination at all times. That keeps your entire synth, drum machine, and groovebox collection wired in and ready. Selecting an instrument takes a single button press instead of a cable swap behind the desk. Your interface or mixer only ever needs one free stereo input.

Fully Reversible Routing

Because the circuit is entirely passive, the Synth Buddy works in both directions. Reversed, it becomes a one-to-ten splitter that sends a single source out to as many as ten destinations. That makes it just as useful for feeding several pedal chains, effects loops, or outboard processors. One box covers both switching and splitting duties.

Transparent Passive Signal Path

With no active electronics in the path, the Synth Buddy passes audio with zero added color. There is nothing to power, nothing to introduce noise, and nothing to fail over time. The signal you select arrives exactly as the instrument delivered it. Purists appreciate a switcher that stays completely out of the way of the tone.

Practical Rear-Panel Layout

All of the inputs and the output live on the rear panel as vertically stacked pairs of quarter-inch sockets. The tidy layout keeps a wall of synth cables organized and easy to trace. Its compact desktop chassis measures roughly 7.5 by 4.1 by 3.1 inches, so it fits neatly beside a keyboard or interface. Everything you need stays within reach on a crowded desk.

Built to Sit on Your Desk

Made for hands-on studio use where instruments change constantly, the Synth Buddy is always at the center of the action. Its solid enclosure survives daily switching and the clutter of a working setup. The distinctive blue finish makes it easy to spot in a busy rig. It is small enough to travel yet sturdy enough to stay put.

Who the Synth Buddy Is For

Synth collectors and hardware producers use it to keep every instrument patched and ready to audition. Guitarists reverse it to route one signal through multiple pedal and effects chains. Engineers value the transparent, power-free switching that never touches the tone. For anyone tired of re-cabling a line-level setup, the Synth Buddy turns source changes into a single button press.
