Our Studio Collection guitar hanger works great for most 5- string and 6-string bass guitars with a nut width of 2" (5.1cm) or less. To ensure the safety of your bass guitar, we don't recommend using our hanger with most 4-string and Jazz style bass guitars due to their much more narrow neck width. For compatible bass guitars with asymmetrical headstocks, the body swivels to ensure your bass guitar hangs securely and looks great on the wall.
