Mandolin Guitarophone (Marxophone)

Mandolin Guitarophone (Marxophone)


The Marxophone is a fretless zither played via a system of metal hammers. It was invented by Charles Marx in 1912. It features two octaves of double melody strings in the key of C major (middle C to C”).

I bought my instrument from a pawn shop in Philadelphia. It was made between 1915 – 1920 by the Oscar Schmidt Company in Jersey City, NJ. I had to do some work on it to get it back into a playable state (replacing zither pegs and strings), but I think it was worth it.

NOTE: My instrument is “technically” not a Marxophone because the Oscar Schmidt Company didn’t own the rights to the Marxophone name until they merged with the Phonoharp Company in 1926.


– Hammer: The classic Marxophone sound
– Pick: Picked with a guitar pick. A classic fretless zither sound.
– Pick – Unison: All Pick samples being triggered at the same time.
– Hammer Swarm 1: The Hammer sound from above, but 4 voices simulatenously looping.
– Hammer Swarm 2: The Hammer sound from above, but 15 voices simulatenously looping.
– Hammer Swarm 3: A media composer pad: the Hammer sound from above heavily processed to create a cinematic pad.
