||Zollo’s Wooden Whistles
Zollo’s wooden whistles are made out of collected tree branches that are then cut and drilled to be hollow and then carved out to resemble a train whistle.
This unique design produces a great sound that is a lower pitch than a standard referee whistle with a more hollow and mellow sound.
Each whistle though, is a different size, creating the option for higher and lower sounds. The longer the whistle, the lower the sound and the shorter the whistle, the higher the sound.
