The ROSE Plus Cajon recreates a traditional tone. It's slightly larger than the ROSE. It features an adjustable wire system. The four strings resonate from low to high notes, creating a traditional sound. Adjust the tension for a crisp sound by tightening it, or for a more open tone by loosening it, creating the perfect sound. Its simple sound allows for a wide range of expression, making it ideal for collaboration with guitar and other instruments. The meticulous construction ensures strength across the entire playing surface, reducing stress during performance and making it a cost-effective cajon that players will enjoy for years to come. The included backpack-style case makes it easy to carry.
