Two foldable integrated Auto Grip systems securely hold the instruments in place. The improved AGS fork is designed to accommodate a wider range of guitar neck sizes from 40 mm to 52 mm (1.57" to 2.05"), including classical, acoustic, electric, and bass guitars. The attached NINA (Narrow Instrument Neck Adjustment) is specifically designed to increase the thickness of the AGS arms to accommodate narrow neck instruments starting from a minimum size of 28 mm (1.10"), such as banjos and mandolins. The instant height-adjustable coupling with locking pin allows for quick, easy, and secure adjustments to the stand height. The foldable backrests with multi-position adjustment securely support the instrument and can be collapsed for transport.
