The RVraiser guitar support or guitar rest combines maximum flexibility with an intuitive and save operation. In daily practice, details often make the difference. The suction cups are the connecting element between instrument and the raiser. They need to guarantee a safe and secure hold on curved surfaces with different shapes and curves. At the same time, the player has to be able to remove them easily and without causing any damage to fine woods or sensitive varnishing. We put a lot of effort in experimenting with suctions cups of different diameters, elasticity, adherence and approaches for applications that help operating the cups. The result is a guitar support that can be mounted safely to guitar bodies of different shapes starting from a depth of 9 cm. Even a depth of only 7 cm is possible with the optional smaller suction cups. With the integrated assistance, it can be removed easily. Even a combination with a protective film e.g. for especially sensitive varnishing is no problem.
