Musician Bernth, who enjoys experimenting with musical instruments, created a homemade 21-string guitar from a standard Ibanez dreadnought acoustic guitar, adding seven rubber band “strings” below the sound hole and eight above the low E string. He then used the augmented instrument to play his gorgeous instrumental single, “Serenade.”. Berth said he liked the sound, but it was a bit unwieldy.
The soft rubber strings blend nicely with the steel strings. They almost sound like a pizzacato cello. …Navigating all these strings was a huge challenge.
